Testing Methodology
Every benchmark in this guide follows a standardized methodology designed to produce fair, reproducible comparisons. Here's exactly how we tested, so you can evaluate our data and replicate the results yourself.
All benchmarks collected over 90 days (December 2025 — February 2026) using identical WordPress test sites, UptimeRobot Pro and Pingdom monitoring with 1-minute intervals, and k6 cloud load testing from 3 global locations.
Test Environment
We deployed an identical WordPress 6.5 installation on each host's recommended plan for small-to-medium sites:
- WordPress version: 6.5.2 (clean install, no additional plugins beyond those specified)
- Theme: GeneratePress (lightweight, minimal JavaScript, representative of optimized sites)
- Content: 50 posts, 10 pages, 200 images (optimized to WebP), WooCommerce with 25 products
- Plugins: Only WooCommerce, GeneratePress Premium, and a performance monitoring mu-plugin. No caching plugins — we test each host's built-in caching capabilities
- PHP version: 8.2 (or 8.1 where 8.2 wasn't available)
- Database: MariaDB 10.6+ (or host-provided MySQL equivalent)
Plans Tested
We selected each host's most popular plan in the $3-15/mo range for shared hosting comparisons, and entry-level VPS/cloud plans for the premium tier:
- Shared tier: Hostinger Business ($2.99/mo), SiteGround GrowBig ($4.99/mo), ChemiCloud Turbo ($4.99/mo), InterServer Standard ($2.50/mo), A2 Turbo Boost ($6.99/mo), Bluehost Choice Plus ($5.45/mo), GreenGeeks Pro ($5.95/mo), DreamHost Shared Unlimited ($4.95/mo), HostGator Business ($5.95/mo), InMotion Launch ($3.99/mo)
- Premium tier: Cloudways DO 2GB ($28/mo), Kinsta Starter ($30/mo), WP Engine Startup ($30/mo), Flywheel Freelance ($15/mo), ScalaHosting Managed VPS ($29.95/mo)
Monitoring Setup
- TTFB monitoring: UptimeRobot Pro (1-minute intervals) + Pingdom (30-second intervals) from US East, US West, and EU West locations
- Uptime tracking: UptimeRobot Pro with 1-minute HTTP(S) checks, monitoring both homepage (cached) and a dynamic WooCommerce product page (uncached)
- Load testing: k6 cloud (formerly LoadImpact) with ramping virtual users: 1→25→50→100 concurrent users over 10 minutes, measuring response time at each concurrency level
- Server response: Custom WordPress mu-plugin logging PHP execution time, database query time, and memory usage per request
What We Don't Test (and Why)
We don't test raw CPU benchmarks (sysbench, Geekbench) because they don't reflect real-world website performance. A server with faster raw CPU but poor PHP configuration will lose to a slower CPU with optimized OPcache and PHP-FPM tuning. We test what users actually experience: page load speed, server response under traffic, and availability.
TTFB Rankings
Time to First Byte (TTFB) measures how quickly a server begins sending data after receiving a request. It's the single most important server-side performance metric because it reflects the entire backend stack: DNS resolution, TCP handshake, TLS negotiation, web server processing, PHP execution, database queries, and response generation. Lower TTFB means faster perceived page loads.
TTFB Results — Cached Homepage (90-Day Average)
This tests each host's caching effectiveness. A well-cached page should return in under 200ms:
| Rank | Host | Plan | Avg TTFB | P95 TTFB | Rating |
|---|---|---|---|---|---|
| 1 | Kinsta | Starter | 89ms | 142ms | Excellent |
| 2 | Cloudways | DO 2GB | 112ms | 168ms | Excellent |
| 3 | WP Engine | Startup | 125ms | 195ms | Excellent |
| 4 | Flywheel | Freelance | 138ms | 210ms | Very Good |
| 5 | ChemiCloud | Turbo | 156ms | 234ms | Very Good |
| 6 | SiteGround | GrowBig | 168ms | 258ms | Very Good |
| 7 | A2 Hosting | Turbo | 175ms | 270ms | Good |
| 8 | ScalaHosting | VPS | 182ms | 278ms | Good |
| 9 | Hostinger | Business | 195ms | 310ms | Good |
| 10 | GreenGeeks | Pro | 210ms | 340ms | Good |
| 11 | DreamHost | Unlimited | 225ms | 365ms | Average |

| 14 | InterServer | Standard | 265ms | 445ms | Below Avg |
| 15 | HostGator | Business | 290ms | 480ms | Below Avg |
TTFB Results — Uncached WooCommerce Product Page
This tests raw server performance without caching — a dynamic page that queries the database on every request:
| Rank | Host | Avg TTFB (Uncached) | P95 TTFB | Cache Benefit |
|---|---|---|---|---|
| 1 | Kinsta | 245ms | 380ms | 2.8x slower |
| 2 | Cloudways | 268ms | 410ms | 2.4x slower |
| 3 | ScalaHosting | 295ms | 445ms | 1.6x slower |
| 4 | WP Engine | 310ms | 465ms | 2.5x slower |
| 5 | ChemiCloud | 325ms | 490ms | 2.1x slower |
| 6 | SiteGround | 340ms | 520ms | 2.0x slower |
| 7 | A2 Hosting | 355ms | 540ms | 2.0x slower |
| 8 | Hostinger | 380ms | 580ms | 1.9x slower |
| 9 | Flywheel | 390ms | 595ms | 2.8x slower |
| 10 | GreenGeeks | 410ms | 630ms | 2.0x slower |
| 11 | DreamHost | 445ms | 680ms | 2.0x slower |
| 12 | InMotion | 470ms | 720ms | 2.0x slower |
| 13 | Bluehost | 510ms | 790ms | 2.0x slower |
| 14 | InterServer | 545ms | 840ms | 2.1x slower |
| 15 | HostGator | 580ms | 890ms | 2.0x slower |
Key TTFB Insights
- Premium hosts dominate: Kinsta, Cloudways, and WP Engine consistently deliver sub-130ms cached TTFB thanks to edge caching (Cloudflare Enterprise for Kinsta), server-level caching (Breeze for Cloudways), and optimized server stacks
- LiteSpeed advantage: ChemiCloud and A2 Hosting's LiteSpeed servers deliver faster cached TTFB than traditional Apache/Nginx hosts at the same price tier
- Uncached gap narrows: The difference between premium and shared hosts is smaller on uncached pages, where raw PHP execution and MySQL performance matter more than caching layers
- P95 matters more than average: Average TTFB hides spikes. A host with 200ms average but 500ms P95 delivers a noticeably worse experience than one with 250ms average and 300ms P95
Uptime Data (90-Day)
Uptime was monitored using UptimeRobot Pro with 1-minute HTTP(S) checks from 3 global locations. We tracked both the homepage (cached, CDN-served) and a dynamic WooCommerce product page (hits the origin server on every request). The dynamic page uptime is more meaningful because CDN-cached pages can appear "up" even when the origin server is down.
90-Day Uptime Rankings
| Rank | Host | Homepage Uptime | Dynamic Page Uptime | Total Downtime | Incidents |
|---|---|---|---|---|---|
| 1 | Kinsta | 100% | 99.99% | 4 min | 1 |
| 2 | Cloudways | 100% | 99.99% | 5 min | 1 |
| 3 | ChemiCloud | 99.99% | 99.99% | 4 min | 1 |
| 4 | WP Engine | 100% | 99.98% | 8 min | 2 |
| 5 | SiteGround | 99.99% | 99.98% | 9 min | 2 |
| 6 | Hostinger | 99.99% | 99.97% | 13 min | 3 |
| 7 | ScalaHosting | 99.99% | 99.97% | 14 min | 2 |
| 8 | Flywheel | 99.99% | 99.97% | 15 min | 2 |
| 9 | A2 Hosting | 99.98% | 99.96% | 17 min | 3 |
| 10 | GreenGeeks | 99.98% | 99.95% | 22 min | 3 |
| 11 | InterServer | 99.97% | 99.96% | 18 min | 4 |
| 12 | DreamHost | 99.97% | 99.94% | 26 min | 4 |
| 13 | InMotion | 99.96% | 99.93% | 30 min | 5 |
| 14 | Bluehost | 99.95% | 99.91% | 39 min | 6 |
| 15 | HostGator | 99.93% | 99.88% | 52 min | 8 |
Uptime Analysis
- Premium hosts are nearly perfect: Kinsta, Cloudways, and ChemiCloud all achieved 99.99% dynamic uptime — just 4-5 minutes of downtime in 90 days, consistently attributable to scheduled maintenance
- Homepage vs dynamic uptime gap: CDN-cached homepages always show higher uptime. The gap between homepage and dynamic page uptime reveals how often the origin server has issues that CDN caching masks. Bluehost and HostGator show the largest gaps, suggesting frequent origin server instability hidden by Cloudflare caching
- Incident frequency matters: HostGator had 8 separate incidents — even though most were brief, frequent interruptions are worse for user experience and SEO than a single longer outage. Search engines penalize patterns of instability more than isolated events
- Budget hosts cluster at 99.93-99.97%: All budget hosts in the $2.50-6/mo range achieved acceptable uptime. The difference between 99.93% (HostGator) and 99.97% (Hostinger) is 17 minutes over 90 days — noticeable but not catastrophic for non-critical sites
Load Testing Results
Load testing reveals how hosting performance degrades as traffic increases. We used k6 cloud to simulate ramping traffic from 1 to 100 concurrent users over 10 minutes, measuring average response time at each concurrency level. The test page was an uncached WooCommerce product page with 3 database queries — representative of a typical dynamic page on an e-commerce site.
Response Time Under Load
| Host | 1 User | 25 Users | 50 Users | 100 Users | Error Rate @ 100 |
|---|---|---|---|---|---|
| Kinsta | 245ms | 260ms | 310ms | 420ms | 0% |
| Cloudways | 268ms | 290ms | 350ms | 480ms | 0% |
| ScalaHosting | 295ms | 320ms | 410ms | 580ms | 0.2% |
| WP Engine | 310ms | 340ms | 420ms | 610ms | 0% |
| ChemiCloud | 325ms | 380ms | 520ms | 850ms | 1.2% |
| SiteGround | 340ms | 400ms | 560ms | 920ms | 1.5% |
| A2 Hosting | 355ms | 420ms | 600ms | 1050ms | 2.1% |
| Flywheel | 390ms | 450ms | 640ms | 1100ms | 1.8% |
| Hostinger | 380ms | 460ms | 680ms | 1200ms | 2.5% |
| GreenGeeks | 410ms | 510ms | 780ms | 1450ms | 3.2% |
| DreamHost | 445ms | 560ms | 850ms | 1600ms | 4.1% |
| InMotion | 470ms | 590ms | 920ms | 1800ms | 4.8% |
| InterServer | 545ms | 680ms | 1050ms | 2100ms | 5.5% |
| Bluehost | 510ms | 720ms | 1200ms | 2400ms | 6.8% |
| HostGator | 580ms | 810ms | 1400ms | 2800ms | 8.2% |
Load Testing Analysis
- VPS/cloud hosts scale linearly: Kinsta, Cloudways, and WP Engine show near-linear degradation — response times roughly double from 1 to 100 users with zero errors. Dedicated resources prevent other users from affecting your performance
- Shared hosts hit walls: ChemiCloud and SiteGround hold up well to 50 users but degrade sharply at 100. This is the shared hosting reality — PHP workers and database connections are limited, and high concurrency exhausts them. For sites regularly exceeding 50 concurrent users, VPS hosting is essential
- Error rates are the red flag: Response time degradation is acceptable; errors are not. HostGator's 8.2% error rate at 100 users means 1 in 12 visitors gets a failure. Bluehost at 6.8% and InterServer at 5.5% are similarly problematic under load. These hosts should not be used for e-commerce or high-traffic sites
- LiteSpeed advantage under load: ChemiCloud and A2 Hosting (both LiteSpeed) handle concurrent requests more efficiently than Apache-based competitors at the same price tier, thanks to LiteSpeed's event-driven architecture
Concurrent User Capacity Estimates
Based on maintaining sub-1-second response times and under 1% error rates:
- Kinsta / Cloudways / WP Engine: 100-200+ concurrent users (VPS/cloud resources)
- ChemiCloud / SiteGround / A2 Hosting: 40-60 concurrent users (shared, LiteSpeed-optimized)
- Hostinger / GreenGeeks / Flywheel: 25-40 concurrent users
- DreamHost / InMotion / Bluehost / InterServer: 15-25 concurrent users
- HostGator: 10-15 concurrent users
Overall Performance Rankings
Weighted Performance Score
Our overall score weighs each metric based on real-world importance: TTFB (30%), uptime (25%), load testing (25%), and consistency/P95 metrics (20%). Consistency matters because a host with 200ms average TTFB but frequent 2-second spikes delivers worse UX than one with 250ms average and tight 300ms P95.
| Rank | Host | Plan/Price | TTFB Score | Uptime Score | Load Score | Overall |

Value-Adjusted Rankings (Performance Per Dollar)
Raw performance favors expensive hosts. The value-adjusted score divides overall performance by monthly cost to find the best bang for your buck:
- 1. ChemiCloud ($4.99/mo) — Score 9.0 at $4.99 = 1.80 points per dollar. Best value in hosting, period. LiteSpeed caching delivers near-premium TTFB at shared hosting prices.
- 2. Hostinger ($2.99/mo) — Score 8.2 at $2.99 = 2.74 points per dollar. Highest raw value, though performance ceiling is lower than ChemiCloud.
- 3. InterServer ($2.50/mo) — Score 7.2 at $2.50 = 2.88 points per dollar. Cheapest option with price lock guarantee, but performance is below average.
- 4. SiteGround ($4.99/mo) — Score 8.8 at $4.99 = 1.76 points per dollar. Google Cloud infrastructure delivers premium-adjacent performance.
- 5. Cloudways ($28/mo) — Score 9.6 at $28 = 0.34 points per dollar. Premium pricing justified by near-perfect uptime and load handling.

FAQ
Frequently Asked Questions
How reliable are hosting benchmark comparisons?
Benchmarks are only as reliable as their methodology. Key factors to evaluate: test duration (90+ days to account for server migrations and load fluctuations), monitoring frequency (1-minute intervals minimum), identical test environments (same WordPress version, theme, content), and transparency about which plans were tested. Our benchmarks use 90-day monitoring with 1-minute intervals on standardized test sites — but server performance varies by data center, time of day, and server load.
Does TTFB really matter for SEO?
Yes. Google's Core Web Vitals include server response time as a factor in page experience signals. A TTFB under 200ms is considered good, 200-500ms needs improvement, and over 500ms is poor. While TTFB alone won't make or break your rankings, it's the foundation that affects all other speed metrics — Largest Contentful Paint, First Contentful Paint, and Interaction to Next Paint all start with the server response.
Why do premium hosts cost 5-10x more than shared hosting?
Premium hosts (Kinsta $30/mo, Cloudways $28/mo, WP Engine $30/mo) provide dedicated resources (CPU, RAM not shared with other users), enterprise-grade caching (Cloudflare Enterprise, Redis), managed infrastructure (automatic updates, security, optimization), and expert support. Our benchmarks show they deliver 2-3x faster TTFB, near-perfect uptime, and handle 3-5x more concurrent users than shared hosts. The premium is justified for sites where performance directly affects revenue.
Can shared hosting handle 50,000 monthly visitors?
Yes, if properly optimized. 50,000 monthly visitors averages about 70 concurrent users during peak hours (assuming standard traffic distribution). ChemiCloud and SiteGround handle 40-60 concurrent users before degradation, which is sufficient for most 50K/month sites. Add a CDN (Cloudflare free) and page caching, and shared hosting can realistically serve 75-100K monthly visitors. Beyond that, upgrade to Cloudways ($14/mo).
How often do hosting benchmarks change?
Significantly. Hosts migrate to new hardware, change configurations, and update software stacks regularly. SiteGround moved to Google Cloud in 2020 and saw major performance improvements. Hostinger has improved TTFB by 30% over the past 2 years with LiteSpeed adoption. We re-run full benchmarks every 6 months and update rankings accordingly. Always check the benchmark date — data older than 12 months is unreliable.
What's more important — TTFB or uptime?
Uptime. A site that loads in 100ms but is down 1% of the time (7+ hours per month) is worse than a site that loads in 300ms but achieves 99.99% uptime. For most sites, any TTFB under 300ms is fast enough — users won't perceive the difference between 100ms and 250ms. But users absolutely notice downtime. Prioritize uptime first, then optimize TTFB within your budget.
