Modsecurity not compatibel with nginx

Hi,

Just debugged some extreem errors.
When you install nginx with modsecurity with the default settings nginx become a memory hog (Took 3.1Gb memory instead of 60Mb).
Opening custom httpd configuration took 5-10 seconds while without it is less then a second.

https://developers.google.com/speed/pagespeed/insights/
gave a 20% lesser score.

Restarting nginx took 10-15 seconds while without it is in about 1-2 seconds.
