Key Findings
- Cloudways delivers the best value-to-speed ratio: 128ms TTFB at $22/month — faster than hosts charging 3x more
- Kinsta is the fastest overall: ~80ms cached TTFB on Google Cloud C2 premium-tier
- Shared hosting degrades badly under load: TTFB jumps 80-232% at 100 concurrent users, while managed WordPress only degrades 19-35%
- Hostinger's 902ms average TTFB is a trade-off for its $2.99/mo price — fine for blogs, not for revenue-critical sites
Why TTFB Is the Metric That Matters Most
Time to First Byte (TTFB) measures how quickly your server starts sending data after receiving a request. Google has confirmed TTFB as a ranking signal, and it directly impacts every other performance metric — Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).
The business impact is measurable:
- +32% bounce rate when page load goes from 1s to 3s
- +90% bounce rate at 5-second load times
- 8.4% conversion increase for every 0.1s improvement in retail
- 53% of mobile users leave if a page takes over 3 seconds
- 47% of all users expect pages to load in under 2 seconds
In other words: your hosting speed directly impacts your revenue. Here's how the major hosts stack up.
The 2026 TTFB Benchmarks: Head-to-Head
TTFB Performance Comparison (12-Month Average)
| Host | TTFB (Idle) | TTFB (100 Users) | Degradation | Price |
|---|---|---|---|---|
| Kinsta (GCP C2) | ~80ms | ~95ms | +19% | $35/mo |
| Cloudways (DO Premium) | 128ms | 172ms | +34% | $22/mo |
| SiteGround (Google Cloud) | <220ms | ~280ms | +27% | $4.99/mo* |
| WP Engine | ~120ms | ~156ms | +30% | $25/mo |
| Bluehost | ~350ms | ~620ms | +77% | $4.99/mo* |
| Hostinger | 902ms | ~1400ms+ | +55% | $2.99/mo* |
*Intro pricing. See Average Cost of Web Hosting 2026 for renewal rates.
The clearest pattern: price doesn't predict speed. Cloudways at $22/mo outperforms WP Engine at $25/mo. SiteGround at $4.99/mo intro delivers competitive managed-WordPress-class TTFB on shared infrastructure.
Uptime: Which Hosts Stay Online?
Uptime is the foundation — a fast site that's offline is worthless. Here's the 12-month data:
12-Month Uptime Comparison
| Host | Uptime | Allowed Downtime/Year | Infrastructure |
|---|---|---|---|
| Kinsta | 99.99% | 52.6 minutes | Google Cloud C2 |
| SiteGround | 99.99% | 52.6 minutes | Google Cloud |
| Cloudways | 99.99% | 52.6 minutes | DigitalOcean/AWS/GCP |
| Hostinger | 99.9% | 8.76 hours | Own data centers |
| WP Engine | 99.95% | 4.38 hours | Google Cloud + EverCache |
| Bluehost | 99.95% | 4.38 hours | Shared (EIG/Newfold) |
For ecommerce sites processing $500+/day, the difference between 99.99% and 99.9% uptime translates to roughly $144 lost revenue per year — enough to cover the price difference between a budget and premium host.
Load Stability: What Happens When Traffic Spikes
The real test of hosting isn't idle performance — it's how the server handles concurrent visitors. This is where the gap between shared and managed hosting becomes a chasm.
Shared Hosting Under Load
When 100 concurrent users hit a shared hosting site, TTFB degrades 80-232%. That means a 189ms idle TTFB can spike to 400-620ms under traffic. For WooCommerce stores running promotions or blogs going viral, this degradation directly kills conversions.
Managed WordPress Under Load
Managed WordPress hosts with proper caching, dedicated PHP workers, and CDN handle the same load much better:
- Kinsta: +15-25% degradation (from ~80ms to ~95ms)
- Cloudways: +19-35% degradation (from 128ms to ~172ms)
- WP Engine: +20-30% degradation (from ~120ms to ~156ms)
The reason is architectural. Shared hosting provides 1-6 PHP workers per site; managed WordPress typically provides 30-100+. WooCommerce checkout — the most PHP-intensive process — runs at ~187ms on managed hosting vs 450-520ms on shared.
WooCommerce Performance: The Revenue Benchmark
If you run an online store, checkout speed is the metric that matters. Here's how hosts perform under WooCommerce load:
WooCommerce Checkout Response Time
| Host | Checkout Speed | PHP Workers | WooCommerce Rating |
|---|---|---|---|
| Kinsta | ~160ms | 30-100+ | Excellent |
| WP Engine | ~187ms | 30-100+ | Excellent |
| Cloudways | ~200ms | Configurable | Excellent |
| SiteGround | ~250ms | 8-20 | Good |
| Bluehost | ~450ms | 1-6 | Marginal |
| Hostinger | ~520ms | Not published | Marginal |
Recommendation: WooCommerce stores with real revenue should use Kinsta, WP Engine, or Cloudways. Shared hosts (Bluehost, Hostinger) are not designed for the PHP worker demands of checkout processing.
Core Web Vitals Impact
TTFB directly influences Google's Core Web Vitals, which affect search rankings:
- LCP (Largest Contentful Paint): Server speed + CDN determine how quickly the largest content element loads. Sub-200ms TTFB is the foundation for a good LCP score.
- FID (First Input Delay): Affected by server-side processing. Managed hosts with server-level caching reduce FID without requiring WordPress caching plugins.
- CLS (Cumulative Layout Shift): Indirectly affected — faster initial rendering reduces layout shifts.
Managed hosts include server-level caching that improves Core Web Vitals automatically. On shared hosting, you'll need caching plugins (WP Super Cache, LiteSpeed Cache) to achieve comparable results — and even then, the underlying server speed creates a ceiling.
The Speed-to-Price Matrix
Combining TTFB benchmarks with monthly cost gives a clear picture of value:
Performance Value Ranking
| Rank | Host | TTFB | Cost | Speed Score | Value Rating |
|---|---|---|---|---|---|
| 1 | Cloudways | 128ms | $22/mo | 9/10 | Best value |
| 2 | SiteGround | <220ms | $4.99/mo* | 8/10 | Best budget speed |
| 3 | Kinsta | ~80ms | $35/mo | 10/10 | Best raw speed |
| 4 | WP Engine | ~120ms | $25/mo | 9/10 | Strong enterprise |
| 5 | Bluehost | ~350ms | $4.99/mo* | 5/10 | Beginners only |
| 6 | Hostinger | 902ms | $2.99/mo* | 4/10 | Budget blogs only |

Frequently Asked Questions
What is a good TTFB for web hosting in 2026?
A good TTFB is under 200ms. Premium managed hosts like Kinsta deliver ~80ms, Cloudways achieves 128ms, and SiteGround hits under 220ms. Budget shared hosts range from 350ms to 900ms.
Which web host has the best uptime in 2026?
SiteGround, Cloudways, and Kinsta all deliver 99.99% uptime — allowing only 52.6 minutes of downtime per year. WP Engine and Bluehost at 99.95% allow 4.38 hours annually.
How much does hosting speed affect my business?
A 1-second delay increases bounce rate by 32%. A 0.1-second improvement equals 8.4% more conversions for retail. 53% of mobile users leave if a page takes over 3 seconds.
Is shared hosting fast enough for WordPress?
For sites under 10,000 monthly visits, yes. Under load (100 concurrent users), shared hosting TTFB degrades 80-232% while managed WordPress degrades only 19-35%. Revenue-generating sites should use managed hosting.
Bottom Line
The 2026 benchmarks are clear: managed WordPress hosting delivers 2-3x better performance than shared hosting, with far less degradation under load. The sweet spot for most businesses is Cloudways ($22/mo for 128ms TTFB), while performance-first teams should choose Kinsta (80ms TTFB at $35/mo). Budget-conscious buyers get surprisingly good speed from SiteGround's Google Cloud infrastructure at $4.99/mo intro pricing.
