A good TTFB value should be less than 200ms for better search results. Time to first byte (TTFB) is to measure the server response. It measures the time when a visitor or client requests the web server and the first byte received by the user’s browser.
Based upon the type of content, the quality of TTFB values also changes. Static content TTFB expected to be below 100ms for the best score. For dynamic pages, it can be between 200 to 500ms.

In this case study, we will see whether TTFB metric using DreamHost’s DreamPress premium plan is low or high.
Test Site – DreamPress and TTFB
The WordPress site we are testing is on the latest version of 5.8. It is using the free version of Cloudflare CDN. Rocket Loader and Brotli compression used. No other minification or caching methods used from Cloudflare. The server is a location in the US.
37 plans installed on the site. Out of the 28 are active. For minification, we are using the Fast Velocity Minify (FVM) plugin.
Caching done by the premium WP Rocket plugin with default settings. HTML, JS, CSS minification feature in WP Rocket disabled and taken care of by FVM.

DreamPress and TTFB – Test Study Scenario
We cleared all the caches on the website. These included FVM, WP Rocket (both normal and OPCache), and DreamPress Varnish cache.
Cloudflare cache also cleared. We were using the WebPageTest speed testing tool to measure the time-to-first-byte timings. We used 9 different server locations to test the efficacy of DreamPress on TTFB.
The following is the table for one web page.
|2||Sao Paulo, Brazil||545|
|4||Cape Town, South Africa||1352|
Since the server is located in the US, we had the best TTFB time from Virginia. It was 340 ms. We tested the page twice or thrice when the TTFB values were very large to get an average value.
The highest TTFB value was from CapeTown, South Africa. It had a value of 1.352s. The other server locations were between 350 to 750ms.
Keeping in the good values of TTFB for static content from Google as a benchmark. We can say that the TTFB score was average.
You can see the actual time to first byte metric value in the WebPageTest on the details tab. When you click the first result and check details, you should see the actual time.
The above results reported are as of summary page. It will be little higher as compared to the actual value. But still as we can see above, TTFB is little higher using DreamPress.
Though the server response depends on the number of plugins, type of plugins, JS and CSS resources used, display, and video ads, the initial server response time is mainly dependent on the type of server configuration.
The location also plays a major role in getting good TTFB values. The amount of HTML page size after conversion creates higher TTFB values.
But on experience with DreamPress for over a year, the TTFB score was not that great with this current plan. Either a better plan needed, or we can use the APO features of Cloudflare for the best TTFB results.
