We've been doing some loaddb testing and have found that when we add a
second processor (Intel PIII 1 Ghz) the loaddb takes nearly twice as long to
run.

The loaded DB resulted in about 17GB being used.

Auditdb took about the same amount of time to run with 2 processors as with
1.

Tested with TSM 4.2.0.0 and 4.2.1.11 on W2K.

With 4.2.0.0 the load took 1hr  50 min with 1 processor, 3hr 44 min with 2
processors.

Withe 4.2.1.11 the load took 2hr 44m with 1 processor, 4hr 45 min with 2
processors.

All of the loads were done from the same unloaded db.

CPU utilization with one processor was constantly near 100%, with 2
processors each was running around 50%.

Has anyone ever come across this?

Does this seem like a bug in loaddb?

Thanks,
