I would also be looking at the scheduler and OS. With that amount of
"timecritical processes" you need a OS with a sched that are up to the
task along side with IO. (not just disk IO)

Load is not that good of a messurement for this. There should be other
tools that shows how well it is working. Load should more just be
considered as an indicator when it goes haywire.

There are a reasons why you just run one service per server in the "real
world".

I would not even consider to run 24 csservers on a single server. The more
csservers you put in, the more stress it will be for the OS. And since you
only uses aprox 25% of all slots. go down to 8 servers and move your way
up until you find when the issues occur. Then find the reason why it
occured.

Setting up AMXX ontop of that will lead to even more workload for the OS,
especially if you fork something or uses it to connect and process data to
and from a db.

Might be worth mentioning that you might need to look at the network
configs of the OS.

I constantly upgrade my servers whenever I find (or think I have) an
improvement to the scheduler. But then again, I am on FreeBSD. Once 7.0 is
released, I will switch all my servers to that OS and the new scheduler.
