We have tsm server 4.2.1 running under solaris 2.8 on a sun 3500.
Had plenty of memory (2gb) and a reasonable amount of disk. However,
performance even with a gigabit ethernet was less than adequate.
Acting on a couple of replies received from this list, I modified the vfstab and changed
the database, log, and stgpool file systems to "forcedirectio".
Throughput went up by a factor of five or more for almost all clients. Clients
with backups of a few large files, showed an increase of fifteen times
throughput.
Thought this info might help someone.
