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.
