ZF2 Optimize for high traffic

Question

My ZF2 application seems to be extremely slow when more than 3 users are using it at the same time.

I profile my code with xdebug and webgrind and non of my function

Answer 1

All of the above and using some kind of opcode caching like APC / Opcache it will speed things up. But yes ZF 2 seems to be very slow unfortunately even more slow then ZF 1 :(

Also the module config cache speeds things up, you cannot have any closures though to make this working ;)
