this enquiring mind would like to know a bit more info: - what was updated and where - surely there's some details in the change request? - what is the TSM server, version, OS, hardware, etc? Is that where the update went? - what/where is the client? - I gather it's file backups from the AIX boxes that's slow? But the Windows ones are OK? What's the difference other than platform - do they go to different storage pools?
