SiteGround Speed Test
Check how fast your SiteGround site really responds — TTFB, DNS, connection and caching, measured in about five seconds.
How fast is SiteGround?
SiteGround averaged 230 ms TTFB in our tests, running on Google Cloud · NGINX · SuperCacher.
Your own result depends on your plan, your site's code and whether page caching is switched on. Run the test above on your SiteGround site to see where you stand.
Google treats a TTFB under 800 ms as acceptable. We recommend under 400 ms; the fastest hosts we test stay under 250 ms.
How to speed up a SiteGround site
- Turn on full-page caching — a caching plugin or your host's built-in cache removes most server work.
- Enable Brotli or Gzip compression so HTML, CSS and JS travel faster.
- Put a CDN in front (Cloudflare's free plan works) to cut network latency for distant visitors.
- Trim heavy plugins and themes that add database queries on every page.
- Upgrade to a higher plan if your TTFB is still over 400 ms with caching on.

Frequently asked questions
How do I check my SiteGround server speed?+
Enter your domain in the speed test above. We measure DNS lookup, TCP connect, TLS handshake and Time to First Byte from our server and grade the result from A to F.
What is a good TTFB for a SiteGround site?+
Under 200 ms is excellent and under 400 ms is good. Over 800 ms is rated poor by Google and usually means caching is off or the server is overloaded.
Why is my SiteGround site slow?+
The most common causes are no page caching, heavy plugins or themes, an overloaded shared server, and a data centre far from your visitors. The tips under your result point to the likely cause.
Does this test slow down or affect my site?+
No. It makes one normal page request, just like a single visitor.
