Summary

After doing the load balancing in the last post, I pointed the domain to the CNAME record of the balancer and did some Web Speed Tests.

Tried comparing the site speed with and without Clouflare CDN using an older version of that post. I have to say, Cloudflare makes the site slower with longer waiting time resulting in a longer TTFB. With the proxy_cache in Nginx, the site without Cloudflare CDN is generally faster. So the site is now running without Cloudflare CDN.

I ran the tests of the old version of the last post on KeyCDN, the test results I need is shown below. The meaning of the table headers:

CF Dev : The page under Cloudflare Development Mode, where the CDN is used without its caching feature, thus the speed is similar to a site on the CDN visited for the first time when the caching is happening.

: The page under Cloudflare Development Mode, where the CDN is used without its caching feature, thus the speed is similar to a site on the CDN visited for the first time when the caching is happening. CF Cache : The page visited from cloudflare cache.

: The page visited from cloudflare cache. Nginx 1st : The page served directly by the nginx on the server without cached content.

: The page served directly by the nginx on the server without cached content. Nginx Cache : The page served directly by the nginx on the server with saved caches.

: The page served directly by the nginx on the server with saved caches. The page : The loading time of the tested post page, in the other words, the html code of the post. This time includes the time of Blocked , DNS , Connect , SSL , Wait and Receive of the domain per request.

: The loading time of the tested post page, in the other words, the html code of the post. This time includes the time of , , , , and of the domain per request. CSS : The loading time of the stylesheet all.css .

: The loading time of the stylesheet . The images : The loading time of the image taking the longest time to load.

: The loading time of the image taking the longest time to load. Isoo data 1 : The loading time of the first data request of the isso responded with (a json).

: The loading time of the first data request of the isso responded with (a json). Isoo data 2 : The loading time of the second data request of the isso responded with (html code).

: The loading time of the second data request of the isso responded with (html code). Total Time : The total loading time of the whole page with all the elements.

: The total loading time of the whole page with all the elements. Total Time Without Woff2 : Total Time minus the loading time of the two google font woff2 files.

Result

CloudFlare only won two rounds, when something occasional happened. So that result is, almost a total win for bare Nginx. I believe with only one server behind the CloudFlare, Cloudflare will behave worse since there will be some longer paths for CloudFlare to receive responses from thus resulting in a longer waiting time. But CloudFlare is okay as a free service, while I can't expect too much from it with so many users on it. I'm still a user of their DNS. Their DNS is famous for its fast speed.
