Hi,
I’ve run some tests on tools.keycdn.com and it seems that I’m having performance issues on the website in some locations (seems like the further from Germany, the worse it gets, which is weird, since CDN should fix this problem). Is there something more that I should setup on my Cloudflare account?
I’m sending the attachment with the test results:
Any help I can get will be appreciated!
Strictly speaking Cloudflare is not a CDN, but - assuming you are not caching your main page - the cache on the proxies will only speed up cached resources, not TTFB.
I guess your server is in Germany in this case, right? As you said, the farther it is away the longer it will take to get the response.
Considering that 130 milliseconds is a bit I’d assume your server has some room for improvement when it comes to its own TTFB. Alternatively you could also cache your main page and have it served from cache, but whether you can do this really depends on your site’s structure.
Whats the domain?
Note when testing keep in mine the testing tool servers’ locations and configuration too. Sometimes the slowness is due to keycdn tool’s geographic servers as well. You can verify using other tools like webpagetest.org which has advanced features you can use to reveal these additional Google focused pagespeed metrics i.e. Google Lighthouse Report
I wrote a guide for my users which maybe useful to you as well including enabling Google Lighthouse Report testing in WPT https://community.centminmod.com/threads/how-to-use-webpagetest-org-for-page-load-speed-testing.13859/
Cloudflare cache certain static content https://support.cloudflare.com/hc/en-us/articles/200172516-Which-file-extensions-does-Cloudflare-cache-for-static-content- but not dynamic generated html itself by default. TTFB for dynamic requests also reveals the response time from your origin server and it’s backends too i.e. php/mysql response time.
So try testing different urls one your index page (dynamic content if served via php etc) and test a css/js static file and compare your times. Cloudflare by default will accelerate the css/js static file so should be faster. You can check the response headers show by keycdn tools to see if cloudflare cache hit/miss/dynamic status. Re-run the test to warm up cf cache and see too.
But you can tell Cloudflare to cache dynamic/static generated html content to some extent depending on Cloudflare plan you’re on via cache everything page rule but have to be careful to only do this for static html content and not dynamic html content (otherwise you would cache private logged in user content).
Hi, thanks for response, I’m responding from a different account, because I don’t have an option to reply from the one I’ve created this thread for some reason…
Ok, is it possible to cache entire website with Cloudflare? So no matter if a user comes from USA or Germany, the user will always get similar loading times?
Yes, 130ms is not perfect, but I’d like to achieve something similar on all of the locations.
My domain is bareminds.de. It’s a wordpress site.
It is, but that will mean your site will be cached any changes wont be visible until that expires. Is that what you want?
Cloudflare Business plan can do that.
Additionally, if you know javascript you could leverage Cloudflare Workers for more advanced caching that can replicate what CF Business plan does for bypass cache on cookie feature.

Ok, I’ll do some research about Cloudflare Workers, thanks for info

Is there a way to purge Cloudflare cache manually?
Of course there is. Manually and automatically via the API.
Thanks, sorry, that was a dull question, I could’ve googled it myself. Thanks for the help guys!
Cloudflare Wordpress plugin has official support for smarter cache purge when updating / publishing wordpress posts etc Cloudflare – WordPress plugin | WordPress.org
WHAT THIS PLUGIN CAN DO FOR YOU
One-click WordPress-optimized settings
The easiest way to setup Cloudflare for your WordPress site.
Web application firewall (WAF) rulesets
Available on all of Cloudflare’s paid plans, the WAF has built-in rulesets, including rules that mitigate WordPress specific threats and vulnerabilities. These security rules are always kept up-to-date, once the WAF is enabled, you can rest easy knowing your site is protected from even the latest threats.
Automatic cache purge
Occurs when you change the appearance of your website. This means that you can focus on your website, while we ensure that the latest content is always available to your visitors.
(Note: By default, Cloudflare does not cache HTML, and a cache purge is not required on updating HTML content such as publishing a new blog entry).
Well, yes, North American and Asians locations do seem to have a higher latency than Europe, but thats a physical limitation

One thing I seem to notice is the difference in latency between the different locations seems to be smaller when testing directly against the origin.
It might be that the routes between the non-European PoPs of Cloudflare and your host are not the best. In this case you might want to have a look at Argo (Introducing Argo — A faster, more reliable, more secure Internet for everyone) as that would ideally choose better routes, though it is a paid feature.
