The Commonstore log doesnt really say much since there can be a number of
reasons why Commonstore is pausing every 2nd document which is not related to
TSM.
In what way are you seeing the performance decrease when importing data from
another server? How big is the difference in time or MB/s? Have you tried
importing exactly the same data earlier? Or are you comparing two different
imports?
Are the backups also affected, or have you only noticed the performance issue
when it comes to Commonstore and importing from other TSM server?
You didnt mention the version of the TSM API on your Commonstore machine.
As a sidenote, data archiving from Commonstore directly to TSM works great
since you're only storing large BLOB's from SAP which are never checked or
accessed from SAP unless SAP needs to bring back that old archived table data.
However, when using Commonstore for document management of SAP (that is,
storing individual documents) I'd recommend having a content system inbetween
such as IBM CM OnDemand or IBM CM. SAP regularly checks the archive for
availability of documents, and storing them directly in TSM might be a
potential performance issue.

Ärende: [ADSM-L] performance issue with commonstore for sap and tsm 6.2.x
hello,
with new tsm server 6 (now the newest version 6.2.3 on windows 2008) we
see performance issues on archiving sap data with commonstore (cssap)
here is a part of the cssap log

interesting, that after archiving 2 files, there is a pause of 13 to 16
sec every time. so the import of some thousand files takes about 6 hours
or more.
environment
IBM CommonStore for SAP - Server 8.4.0.13, installed on tsm server
TSM Server 6.2.3 , target destination for cssap archives = diskpool
we also see performance issues on importing other data from another tsm
server.
reorg of the tsm database is working.
we do not see any performance issues on migrate, copy or something else
any ideas?
with best regards
