yep, I did consider these things, but I double checked: - 100/Full - The files were compressed when they were backed up, The client is not being taxed decompressing the data stream at all (currently 89% idle) - we started with one thread, but are up to 4 now. Each one is performing pretty pathetically - Data are big files (6x2gB files) - Yes, pinging works, FTP speed between the client and server is fine.

So, the data to the client is not going to be as fast as restoring to the TSM server. Things to consider are... What is the LAN speed and duplex settings for the client? How is the LAN traffic when you are trying to restore? Is compression enabled on the TSM client side? How many channels/threads/mount points are you allowing the client to use? What type of data are you restoring, compress, database data, etc? Can you ping the TSM server from the client? Can you ping the Client from the TSM server? Anyway, I hope this helps! -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Shawn Drew Sent: Wednesday, June 25, 2008 2:47 PM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] Restore performance puzzler 5.4.1 AIX Server 5.3.4 AIX 5.1 Client Performing a 12 gB restore. (6x2gB files) The restore is performing at a rate of about 250-500 KB/s with bursts up to a whopping 750KB/s (Looking at the VTL drive monitor) If we perform the restore locally to the TSM server's file system, it is fast. (20-30 MB/sex) We can FTP the data to the client fast as well, 10-15MB/sec A restore of the same files performed at the client crawls. We are upgrading to 5.3.6, which looks to be the newest AIX 5.1 client we can use. Any ideas?
