I've run into a problem on TSM 6.2.3 on Windows 2008 R2. 32 GB RAM, 4 6-core processors.
Issue: node backup statistics USED to report in the range of 2,000 KB/sec to 10,000 KB/sec night after night for all nodes.
For the last few weeks, the rate is consistently less than 200 KB/sec; night after night.
Daytime tests are also 200 KB/sec or less, when no other server-side work (reclaim, dedup, table re-org, db backup) is running.
I've swapped network interfaces at the server, changed switch ports, changed switches, confirmed the ports are at 1 Gbps/full. Rebooted at least 5 times.
V 6.2.3 was installed 4 weeks before the performance drop.
A backup of a 14 GB file now takes about 90 minutes, but I can copy that same 14 GB file to the server in less than 2 minutes.
I don't see any related TSM interim fixes. IC76984 is related to nodes getting hung and not completing , but backups are successful in my case; just extremely slow.
Some Windows security patches have been installed, forced by our security team.
Anyone else seeing similar behavior? I'm preparing to open a PMR.
