Hi Frank! The first thing to do is check your network. The easiest way to do this is by using FTP. The following command can be done from one AIX node to your server:
ftp your.servername.com ftp> bin ftp> put "|dd if=/dev/zero bs=64k count=10000" /dev/null ftp> quit This will give you a pretty good idea how your network performs. If that's ok, you will have to continue with your AIX environment. Is it paging? Did you tune your gigabit Ethernet adapter? (Jumbopackets on yes) Issue the entstat command four your adapter. Is No mbuf errors larger than 0? If so, then raise thewall value. If all that doesn't help, you will have to start a client trace. You can try sending the instr_client_detail_trace output to this list, there are always people that are willing to help you with this. Another option is opening a call. IBM has a group of people dedicated to performance tuning. I know because I was one of the lucky guys that took a class with one of them.

So I would like to describe our environment once roughly: We have 2 TSM server (Version 5.1.8) which runs both on AIX boxes with AIX 5.1. On the first server is an 3494 library (with 4 3590 drives) connected and on the second server an 3583 (with 3 LTO Ultrium1 drives). The clients (AIX-clients and Windows clients) are connected over fastethernet or gigaethernet. First TSM server has both adapter (fast and giga). The connection between the first and the second TSM server is gigaethernet. Can you give me some tips to increase the performance? I think that are some TSM and AIX options (TCPWindowsize etc on TSM side and son no-Paramter on AIX site). What is a good start for this options?
