Hi!

We recently installed TSM 5.1 on Solaris 2.8.  The performance is terrible
and I can't get any better going to tape than I do to disk.  We already
tried moving from filesystems to raw logical disk for our disk pools.  It
helped some but not enough to make a difference on anything.

I have tuned my server with the following parameters:

bufpoolsize 131072
logpoolsize 2048
movebatchsize 1000
movesizethresh 500
tcpwindowsize 65536
txngroupmax 256
tcpnodelay yes
uselargebuffers yes
selftunetxnsize yes
selftunebufpoolsize yes

What type of performance are others seeing?  Any help would be greatly
appreciated to understand what we are doing wrong.


Thanks!
