in reply to PSGI/Plack unsatisfactory performance

mod_perl

It makes me sad people aren't using it.

I just did a hello world test on my system, a bare apache with mod_php 7, and then that same apache with mod_perl loaded instead. I got 1,500 requests per second more with mod_perl

The following was performed on a relatively low traffic Intel E3-1230 v6 with 64gb of RAM

mod_php for a baseline:

config:
