Definitely more RAM. I've found that it works best with at least two gig.

If the load is in wait state, then you need to cur the number of processses. vmstat will give you the essential information: [EMAIL PROTECTED] ~]$ vmstat procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 1 0 193496 76396 123780 293280 1 2 3 3 2 6 8 1 89 2 This box with 2 GB of ram and 32 children discards about 65000 spams a day. I should probably cut the children down some now, Greylisting has cut the number of concurrent sessions I need to maintain. -- Daniel J McDonald, CCIE # 2495, CISSP # 78281, CNX Austin Energy http://www.austinenergy.com ------------------------------------------------------------------------- Using Tomcat but need to do more?
