What specific HP tuning parameters need to be changed and what values seem
to work best to take advantage of the increased memory?

        Hi

        Ur data txfer rate is low.

        U have to do two things.

        See that u are not on autoneg mode in tcp/ip setup.
        See that u have set performence in dsmserv.opt.
        use compression as yes in dsm.sys file.
        We had upgraded mem in HP boxes from 2gb to 4 gb
        and  network transfer speed improved considerably
        from 14mb/sec to 90mb/sec.

        Again we have all 100mb/sec with all s/w s at 100mb/sec.

        Hope all this info is usefull to u.

        I need some advice on performance issues regarding tsm 4.1.2.0
running on
        a aix 4.3.3 box.

        I've been trying to optimize the network throughput, but without
real
        luck. Then I tried backing up the tsm server through lo0 and I ended
up
        with the following result

        Total number of objects inspected:   49,295
        Total number of objects backed up:   49,295
        Total number of objects updated:          0
        Total number of objects rebound:          0
        Total number of objects deleted:          0
        Total number of objects expired:          0
        Total number of objects failed:           0
        Total number of bytes transferred:     2.45 GB
        Data transfer time:                  546.68 sec
        Network data transfer rate:        4,706.32 KB/sec
        Aggregate data transfer rate:      2,041.05 KB/sec
        Objects compressed by:                    0%
        Elapsed processing time:           00:03:00

        which is not a fantastic throughput.

        I'm backing up to a diskpool of ssa-disks (no raid) and i have a
30GB
        database which has never been defragmented.

        Is it a memory tuning issue?

        Any suggestions are welcome.

        Does anyone know of a new tivoli performance tuning guide? I have a
(not
        up to date) SP performance tuning guide.

        Med venlig hilsen / Regards
