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.
