Hello all, I did a timing test of a DSMSERV UNLOADDB/LOADFORMAT/LOADDB with our 50GB database on a separate system. This test system was an older, single CPU, 500MB RS/6000 and the dump was to a file on disk (approx 22GB). What I'm surprised about is that when we ran the process on the real system (8 CPU SP node, 2GB memory), it is no faster - in fact it might even be slower (I'm not sure yet because it is STILL running from the weekend). The only significant difference is that the real dump/load is using a 3590 tape instead of a file on disk. This note is meant as a warning/heads-up to all of you, but I am also interested to hear of other experiences/timings, and expecially from any developer or support types with access to the source code as to why it wouldn't be running faster on a faster system? Could using 3590 be the problem? (Doesn't 3590 have good stop/start performance numbers?) I don't suppose there are any "sleep 10" statements imbedded in the code for future performance improvement releases ;-). Thanks, Scott Scott McCambly AIX/NetView/ADSM Specialist - Unopsys Inc.
