Hi Rich,

Have you set the spool and rpool buf sizes on the switch to about 10000000
on the server and client ??

I just moved our ADSM server to a new Silver node running AIX 4.3.3 and
our performance for backups is about 1/2 of what it used to be, (old server
was a silver node running 4.2.1.)  Our adsmserver tuning options are the
same (copied over dsmserv.opt from old server, and our no "network options"
are the same (for the similiar no parameters between 4.2.1 and 4.3.3)  Here
is some info from our server node. Its a silver node 4 cpu/332 mhz with 3
gig or RAM.

Backups are SAP/BAckint, no changes have been made to the client
side/backint config files, backups go across SP switch, no changes have
been
made to switch tuning either.
Backups go to 3494/3590 drives (B12 models), 4 drives per backup client
