I have a dedicated server running FreeBSD 7.2 64bit.
When I enable APC on Apache (Prefork), I notice in 'top' and in the SIZE column, it grows from 110MB to 384MB. I realize this is shared memory and shared across all apache processes.
The problem I have is this :
Each process size (in the 'RES" column) grows from 25mb to almost 100mb EACH.
Why does this happen?
My processes never grow any larger than 30mb without APC. I only have 8gb ram so if each apache process takes up 100mb, I have to set my 'MaxClients' to 50 in order for my server not to use swap.
