Hi Eric,
I'm running an H50 with 2GB memory and 4 CPU's, a 10GB Db (80% utilized) on
SSA disks
and get about 76 objects per second.
I have seen big improvements when doing an UNLOADDB/LOADDB - so I'm going to
do this once
or twice a year. This takes 5 to 6 hours for our configuration.
HTH
Kind regards
