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 functions seems to be slow so it has to be an optimalisation issue within the zf2 it's self.
For cache I make use of the EdpSuperluminal module by EvanDotPro, this seems to increase the performance of the application.
We make use of nginx reverse proxy but make no sense as well.
I need some good advices to increase the response for high traffic. I speak about 30+ connected user at the same time.
