Anyone else using this platform for IDS?

I am not impressed by performance of 9.40 on this platform so far. It's
only about 25% faster than standard engine on our old AIX box! For
reference the hardware we have:

2x1Ghz CPU, HPUX 11.23, IDS 9.4, rootdbs, datadbs, indexdbs all on same
LV.
6gb ram
EMC array, 4gb cache, part of 6x72gb disk, raid 5 [yes I know, have no
choice at present]

I am comparing that to:
4xCPU, AIX 5
1.5gb ram
No disk array, 3 9gb disks

What's worse is that the AIX system is used by other developers so
testing is impacted by their activity.

I'd like to compare notes with what anyone else in this environment.
