I had a HK server and hosting two domains (A and B) with Cloudflare, but today A is very slow, so I compare with B using same php and following is result:
A domain point to Cloudflare server 220.127.116.11
B domain point to Cloudflare server 18.104.22.168
php file (same server and same file)
Waiting (TTFB): 2.07s
Waiting (TTFB): 351ms
The domain A is much slower than B, so I check with cdn-cgi/trace
Waiting (TTFB): 49ms
Waiting (TTFB): 60ms
You can see A is faster than B, because colo SIN is near than NRT, it make sense.
But, why php (dynamic content) is much slower?
anybody can tell me why? and how to fix this? or any Cloudflare network problem now?
Thanks so much and Happy new year!
