I have some problems with application perfomance. Admins infiltrated between php-fpm and nginx and said that nginx get data with delay (dozens of seconds).
I use PHP 7.0.23, nginx/1.12.1, FreeBSD 10.3-RELEASE-p11
Application logs show that code finish work in second or less.
Does php-fpm have some ready solution? For example set some compile options, build php-fpm and get process that write perfomance logs so i can find root of the problem? Or i just should understand how php-fpm works, add logs where it is required on my own and build php-fpm?
