I just read the requirements for GroupWise 8 (server side/backend) and it does list that GroupWise 8 is a 32 bit application but as far the Operating Systems (Windows and Linux) it does not say it must be 32 bit.

So is 64 bit supported?

Does anybody run GroupWise 8 on 64 bit of Windows 2003/2008 or 64 bit Linux and if does it run any better (aka faster)? Just wondering if taking Groupwise 8 from 32 bit OS with a 4 GB limit to 64 bit OS with 12 GB or more would help. I know the POA does not use much but maybe the OS may do faster job of disk caching and responding.
