Hi Josh,

I'm using a Linux Kernel 2.6.32-21-generic and Apache 2.2.14-worker+modsec embedded.
I did some adjusts into worker apache options based in my cpu and memory

# worker MPM
# StartServers: initial number of server processes to start
# MaxClients: maximum number of simultaneous client connections
# MinSpareThreads: minimum number of worker threads which are kept spare
# MaxSpareThreads: maximum number of worker threads which are kept spare
# ThreadsPerChild: constant number of worker threads in each server process
# MaxRequestsPerChild: maximum number of requests a server process serves

I didn't do any modification on Linux Kernel... but maybe we have some options there.
So i defined:

    StartServers         10
    MinSpareThreads      10
    MaxSpareThreads      30
    ThreadLimit          100
    ThreadsPerChild      100
    MaxClients          500
    MaxRequestsPerChild  0

Most of my contents are static, but have some dynamics ones (which make apache process bigger). I can handle ~1.500 connections per second and ~150 concurrent connections. I have have a limited env for testing.

I didn't test using modsec in a separate computer as reverse proxy... but i will do that and send some results.

Hi Breno,

Can you describe the Linux and Apache tuning you did that you found to
be effective when using gsblookup?
