Maybe someone can help me with a problem.
I have a pretty beefy webserver, with 3 gigs of memory. The load average on
the machine is really high, when apache loads. Disk swapping is also high.
Apache is almost bare with a couple of modules installed. The content I am
deleving is static content. My kernel config is generic also, but I need
some advice on what I can do to get the load down to < 20 (highest I've
seen it was around 200)
