Ubuntu 32-bit or 64-bit?

[Crusty]

I just got a brand new Quad Core Q6600 with 2gb of ram in it that needs to be running Linux, I will be using Ubuntu because that's what I am used to.

[*]100gb mySQL Database
[*]Java Development
[*]VMWare Workstation for C# Developement
[*]Hosting a CVS server
[*]Batch Data Analysis tools run overnight in Java

Are there any massive issues with 64-bit that will prevent me from doing this? I am very comfortable with the CLI so having to install some stuff manually or having to tweak stuff is not an issue,

The only thing I am worrying about really is Java. VMWare can be run with the IA32 libs and a small patch from what I have read.

I currently have plans to increase the ram of this system up to at least 4gb(if not 8gb) as well since a lot of our data analysis tools can be memory intensive if allowed.

Thanks 🙂

Well if your analysis tools require the ability to use >3G of memory in a single process then you have no choice but to use 64-bit binaries for them so at the very least you'll need a 64-bit kernel.

There does appear to be 64-bit java6 packages in Debian sid so they're probably in Ubuntu too. I have no idea how well they work though since I tend to avoid everything Java.
