That's the first time I have heard anyone make that claim. Very certainly I have found Oracle on NT to be slower than on Solaris. I haven't been able to make comparisons with the same hardware though. A small Oracle database with 20 concurrent (client/server) users crawls on NT on a dual CPU 128 Meg RAM Compaq Proliant.

A 10 Gig Database with usually 150 concurrent users gives < 2 second response times on a Sun 1000e with 512 Meg and 4 X 50 Meg CPUs (yes, 50 Meg CPUs).

Even our smaller databases on Sparc 10s and 20s are faster than the small NT one.
