gnu/linux on AMD: 64-bit or 32-bit?

[Josh ChaitinPollak]

We are deploying x64 (amd64) Red Hat Enterprise 4 on HP Proliant  
servers without a problem. The only things I've noticed is that  
Apple's multicast-DNS interface for Java was not 64-bit ready, but I  
submitted a patch to them for that. In addition, the doesn't seem to  
be a 64bit Mozilla plugin for java, Sun recommends you use the 32bit  
JRE and plugin. I'm not sure what the deal with that is, but we don't  
need the plugin on our servers.

Other than that, not complaints. I don't have any info on performance  
differences unfortunately.
