^^^ well, that just screams "you're out of httpd children". You've got
a few options:
* If your app is slow, poke your developers. If it's hitting a
database for every request, see if it actually has to
* If your content is all (or primarily) static, you've just got tons of traffic
coming in. You can add another server to your rotation, effectively
doubling your capacity, place a light-weight server (such as Tux) in
front of Apache, or a Squid instance in front of Apache
* Looks like you still have CPU to spare, so as long as you're not close to
maxing out your memory, you can crank up your MaxClients directive. Note that
the default compile-time hard limit on Unix is 256, so if you need to increase it,
you'll need to recompile apache with something like:
-DHARD_SERVER_LIMIT=1024
Added to your compiler flags (or, you can always tweak include/httpd.h
manually, if you prefer). Once that's set to 1024, you can increase
MaxClients to, say, 384 as a starting point and see where that gets
you. Be advised that by running a large number of children, you run
the risk of running out of memory. Do the math: if
memory-per-httpd-process * # httpd processes >= RAM on system, you'll
likely have issues. I've had great success placing a lightweight
server (Tux, in my case) in front of apache to handle the static
content (images and the like). Of course, this may require you to
patch and recompile your kernel.
My, that's a lot of typing for this hour. =)
