I am trying to optimize apache 2.2 to handle more traffic. The current setup is a box for apache with 32 GB of RAM, 16 processors and SAS drives. Database server has its own dedicated box with similar specifications.
I dedicated a lot of time optimizing queries and tweaking MySQL to get the most out of it. I have notice that my last bottle neck is apache as I would expect to have better response times with such configuration.
With no traffic at all pages generation times is (0.2s~0.5s) with simulated traffic the load jumps to (1+s ~ 5+s). I use the memory_get_usage() function from PHP and I get a 1.6MB per page, but when I check the .top command there is another number:
