Hello Your datatransfer rate seems low. Are you running at 100 mbit and full duplex? Try to ftp a file from the client to the server and check the transfertime, with 100mbit you should get about 10mb/sec
Regards Niklas -----Original Message----- From: Etienne Brodeur [mailto:ebrodeur@;SERTI.COM] Sent: den 5 november 2002 15:44 To: [EMAIL PROTECTED] Subject: Troubleshooting performance issues I have some major performance issues during archive operations. I also have bad performance durning backups, but the backup window is large so they complete without any problems. I can't seem to put my finger on the bottleneck and was wondering if someone had a document to recommend when looking for performance issues? Here is the scenario: TSM 4.2.2.10 server on W2K (SP2) 3 IDE drives. OS - DB - LOG 100 Mbs/Full Duplex (not auto) LTO 3583 SCSI attached to the server Server Options: CommTimeOut 60 IdleTimeOut 30 BufPoolSize 81920 LogPoolSize 512 TxnGroupMax 256 MoveBatchSize 256 MoveSizeThresh 500 UseLargeBuffers Yes NOBUFPREfetch No AuditStorage Yes SELFTUNEBUFpool Yes SELFTUNETXNsize Yes TCPWindowsize 64512 TCPNoDelay Yes There are 10 clients running 4.2.2.x (mostly 4.2.2.0). I have not set any performance settings in the DSM.OPTs. The servers have less than 10 GB of data each. I have 5 of them archiving to tape at the same time and they are all running very slowly: 05-11-2002 01:29:29 ANE4952I (Session: 5848, Node: HY-ORAPED-2000) Total number of objects inspected: 102,322 05-11-2002 01:29:29 ANE4953I (Session: 5848, Node: HY-ORAPED-2000) Total number of objects archived: 86,989 05-11-2002 01:29:29 ANE4961I (Session: 5848, Node: HY-ORAPED-2000) Total number of bytes transferred: 6.46 Go 05-11-2002 01:29:29 ANE4963I (Session: 5848, Node: HY-ORAPED-2000) Data transfer time: 11,875.56 sec 05-11-2002 01:29:29 ANE4966I (Session: 5848, Node: HY-ORAPED-2000) Network data transfer rate: 570.67 KB/sec 05-11-2002 01:29:29 ANE4967I (Session: 5848, Node: HY-ORAPED-2000) Aggregate data transfer rate: 511.71 KB/sec 05-11-2002 01:29:29 ANE4968I (Session: 5848, Node: HY-ORAPED-2000) Objects compressed by: 0% 05-11-2002 01:29:29 ANE4964I (Session: 5848, Node: HY-ORAPED-2000) Elapsed processing time: 03:40:43 This was the fast one, I also have this W2K client: 05-11-2002 07:25:34 ANE4952I (Session: 5906, Node: HY-OSRV-2000) Total number of objects inspected: 8,424 05-11-2002 07:25:34 ANE4953I (Session: 5906, Node: HY-OSRV-2000) Total number of objects archived: 8,364 05-11-2002 07:25:34 ANE4961I (Session: 5906, Node: HY-OSRV-2000) Total number of bytes transferred: 2.76 Go 05-11-2002 07:25:34 ANE4963I (Session: 5906, Node: HY-OSRV-2000) Data transfer time: 2,871.55 sec 05-11-2002 07:25:34 ANE4966I (Session: 5906, Node: HY-OSRV-2000) Network data transfer rate: 1,008.95 KB/sec 05-11-2002 07:25:34 ANE4967I (Session: 5906, Node: HY-OSRV-2000) Aggregate data transfer rate: 97.15 KB/sec 05-11-2002 07:25:34 ANE4968I (Session: 5906, Node: HY-OSRV-2000) Objects compressed by: 0% 05-11-2002 07:25:34 ANE4964I (Session: 5906, Node: HY-OSRV-2000) Elapsed processing time: 08:17:01 Please help me!
