I'd expect roughly equivalent performance on different platforms. I
measured the insert performance a couple of years ago and found
roughly 50 inserts per second on my dual processor, 180MHz PPro
system, which was the same performance as I had on an Ingres
installation on a medium-speed Alpha/OSF-1 box.

Without knowing more about your memory and disk setup, I'll guess that
you can use more memory, can bump buffer size by using "-B 1024" or
something similar, and running without mandatory fsync() (use the "-F"
option). However, istm that your system should do better than 10ips
before you invoke "-F", otherwise you'll just be working around
another underlying problem/bottleneck.

Good luck.
