Dan, you might want to look at the dsmaccnt.log file in the server
directory.
Sorry, it's not user-friendly - but it will tell you where the
bottleneck is.
The file layout is in the admin guide - look up dsmaccnt.log in the
index.
Find the record for the session that is slow (the session has to end
before dsmaccnt will have a record) and pull the fields for total
seconds, commwait seconds, idlewait seconds, and mediawait seconds.
Some light should start to dawn then, as to why it's so slow.
much idlewait: the client is taking a long time to figure something
out. it's not asking for data.
much mediawait: tapes aren't getting mounted in a timely manner, or lots
of tapes are getting mounted repeatedly.
much commwait: normal to see 20-70% - you AIX server is faster than your
network card. But if it's 95%, well, ftp a file between the two and see
what kind of speed reading ftp gives you (ie, with TSM out of the
picture entirely).
Hope this helps.
