Double check your SSA loops, adapter settings, and AIX IO tuning.  This very 
much sounds like a disk IO problem.

This is a 6h1 with 4 processors and 4Gb memory. Disks are SSA, 2 controllers

and 4 full D40's for TSM DB, Logs and disk pools. All disk JBOD. GIG nic

that when at it's peak only 50% utilized.



Cache hit pct is consistently steady at over 99%. Database is 120GB at 33%

utilized.  Database backups are running at about 4.5 hours to complete.

Bufpool size is 524288, which matches the older server and all other options

are also identical to the older server.



Backups themselves seem to have slowed as I've added more clients to backup.

This morning there are still 24 servers running. While on the M80 I never

saw this.



The M80 is similar in configuration, but only 2 CPU's, which is why I pretty

much mirrored it when building this one. The newer system however is pretty

much a dog right now.
