Dear Marc, I am runnin w2k dual p4 1GB mem 3583 scsi based.
The network is GB. Right now I am tunning tcpwindows size buffpoolsize txnbytelimit movetresh movesize txngroupmax The filesystem is filed with small files from 256kb to 15 mb. The higest performance figure was: 2.126.68 network 886,00 aggregate FTP does 20 MB a sec ??? So maybe my LTO is performing lousy ( give me magstar any day for small files ) Any sugestions ? Best Regards, Koen Willems

There are so many variables that asking a generic "how fast should it be?" is rather a pointless pursuit. Instead, follow good practices all around. Tune your server OS to optimum file I/O, clear your network of bottlenecks with best practice standards, and schedule TSM activities to even out the load as much as possible. If you're buying a new server for TSM, buy one with decent memory and CPU resources. If you don't do these things (or don't know how), no amount of fiddling with TSM is going to give you quality throughput speeds. The #1 reason (in my experience) for poor throughput in TSM is bad and/or poorly maintained networks. -- Mark Stapleton ([EMAIL PROTECTED]) Certified TSM consultant Certified AIX system engineer MCSE
