Hi,

The CPU usage (%sys) is extremely high, like 80 - 90%, on the TSM server
(Sun V880 running TSM v5.1.5) during the backup window. Particularly when
TDP R3 clients are attempting their SAP backups via backint / brbackup and
as such the throughput is extremely poor (<9MB/s direct to disk cache via
gigabit network).

The culprit for the high cpu usage is dsmserv and seems to be eating system
resources at the expense of I/O and user. So bascially I'm looking for
recommendations, best practices or experience of the TDP R3 agent to try and
resolve this issue.

BufPoolsize = 512000
LogPoolsize = 8192
MaxSession = 200
TxnGroupMax = 256
SelfTuneBUFPools = No

Any ideas welcome...

Thanks
Sean
