We're running on a Compaq DL 380 G4 with 4GB memory and a RAID1+0 setup with 8 total drives == 4 spindles. Box has proven to be a screamer for other applications, like sendmail ( we run all the mail relays for EDS and EDS's customers ).
/proc/version says:
Linux version 2.6.9-42.0.3.ELsmp ([EMAIL PROTECTED]) (gcc version 3.4.6 20060404 (Red Hat 3.4.6-3)) #1 SMP Mon Sep 25 17:28:02 EDT 2006
python 2.4.3
We're averaging around 35-40 user connections, and here the output from a 60 second run of 'sar':

Thinking something might be spinning, I upped the debug level of my Jabber XCP server to 'debug' for a few minutes.
In those few minutes, 27,822 of these showed up:
Oct 31 12:39:23 plmler7 eds_jabberd[22196]: deliver.c:1203::98311 : DELIVER: type:1, host:yahootest.eim.eds.com, packet:<presence type='subscribed' to='[EMAIL PROTECTED]' from='[EMAIL PROTECTED]'><status>Already Subscribed</status></presence>
All of them with '[EMAIL PROTECTED]' ... I checked his/her roster and all the yahoo gateway entries have subscription='both'
Opinions, thoughts, comments welcome ...
