I have been reading the replies to this, and I have to disagree with most of them. It is better to go with 64-bit now since in the future you may need to run a 64-bit application, and then you would have to switch. You save time and energy by going with 64-bit now.
I know this should be obvious, but I want to make sure that you really realize that you can run 31-bit applications on a 64-bit system, but you cannot run 64-bit applications on a 31-bit system. This kind of thing has a way of sneaking up on you. Someday somebody may buy an application and latter realize that it is a 64-bit application. I have been through a few 16-bit to 32-bit migrations. It is much better to switch early when you have time to work out the problems. Having to migrate when you have an emergency that requires a migration is a real pain. -----Original Message----- From: Lucius, Leland [mailto:[EMAIL PROTECTED] Sent: Saturday, July 12, 2003 3:33 PM To: [EMAIL PROTECTED] Subject: Probly a stoopid ?, but what's "better"...31-bit or 64-bit? One of the first things we told when we setup our guests under VM is to give the guest only as much memory as it needs which is usually quite small. If that's so then not even a 31-bit address space will be needed. So, why not run 31-bit Linux guests? Does it matter one way or the other? Are there performance differences? I know, probably really stupid questions. Just popped into a sleepy brain after a big meal... Leland
