Hi Teemu, 

we use a cluster of two dual athlon servers for the webservers ( which
do loadleveling), with one large mysql for most databases, but also a
Netware cluster for LDAP and fileservices ( the HTML and perl files are
pulled in via NFS ) and a few oracle and ms-sql databases. This serves
up 1000 Intranet users. But this is not a regular internet website type
of usage, but at least 200 users are using this as their main callcenter
application, so the OI applications are rather heavy weight.

You should separate them, I guess. If this is smallscale stuff, then
keep the spawn server settings etc. low. 

Remember the most important tuning rule here: keep your systems from
swapping ! ( under Linux install sysstat package, have sac runnig and
use sar -r, here you should never see more then a few % of swapping. If
you really want to make it fast, keep the system from swapping more than
1 % constantly - 30/40 % constant swapping is already overkill ! )

You should not worry about this ! ( If you are not using a 486-SX 25 MHz
;-) )

Since I am curious: what type of app are you thinking about ? 

later,

Andreas
