I do not use CloudFlare “Cache Everything” because of dynamic content.
But I noticed at my Website which uses “FRA” as CloudFlare-Ray that my TTFB is very very high.
When I call a site which is getting routed through CloudFlare-Ray “FRA” I get a TTFB of about 500ms-600ms
The response Header looks like this:
When I bypass CloudFlare (with curl) my TTFB is at 40ms.
Also when I call other sites which are static (like this one) my TTFB is very good and at about 30ms-40ms
Are there any issues with FRA or anything else what casues this?
On another Page I use Cache Everything and the TTFB also is very high.
Notics: this request is a very lightweight 304 and is a HIT in CloudFlare Cache. It varies very hard and even goes up to about 3s to respond.
