thanks for correcting me.
as always, when it gets low, dirty and hardwired, call Yonik to help :) 

I do not know exactly why, but we tried it a while ago and all our lucene apps were faster
on 32bit jvm

Would you expect it to be faster on 64bit jvm, is it worth digging deeper?

something to the OS, and is generally faster due to shorter pointers and more availyble registers
on 32bit..

Less available registers in 32 bit mode :-)
Right about the larger pointers though... they can make things
slightly slower (cache effects, etc).
