Should there be such a huge difference of NSS filesystem performance on
64-bit OES2 versus 32-bit OES2? In some cases I am seeing 25% or more
slower under 32-bit on the same hardware? The server doesn't have more than
4GB RAM so it can't possibly be the 32-bit memory addressing limitations,
can it?

We really cannot afford to replace all our Netware servers with 64-bit
hardware simply to maintain the same level of NSS filesystem performance
:-( Many of the servers aren't even 2 years old.
