I have moved my website on a bundle NGINX+PHP-FPM. This all works good, but I have noticed one performance issue.
It's delay when I'm asking file via HTTPS.
For example:
I created blank PHP file () and call it via HTTP and via HTTPS.
In HTTPS case I've seen additional ~60-70 ms of response time. And another test:
I've measured page speed of this blank file via HTTP - it's 100/100 score. But via HTTPS the same file score is only 95/100. Page Speed meter complaints on the query time in a second case and it's those additionals 60-70 ms.
I've used Comodo certificate and in the HTTPS test we have rating A+.
How can I fix this issue? Maybe I need a lower score in HTTPS test and accordingly lower secure encryption settings? Thank you for answers!
