[ale] dumb apache/memory question

[Stephen VanDyke]

Ok, since I really can't tell what the problem would be aside from code that
is inefficient and needs to be streamlined, I can only suggest the following
ideas:

if the server is a virthost, bring things down 1 domain at a time and see
where the load drops.
if it's just one big site, try to narrow down what script is causing
problems
add more RAM, yes it really could be time to upgrade to 1GB -> 2GB -> Load
Balancing
