64 bit is the way to go...

The server is up and running. It is a 64-bit Xeon with two processors.

Sorry. the info was cut a little bit here and there. The point here is, it has 2 cpus (see processor 0 and 1 and it is Xeon 2.8 Ghz)

Here is the memory info :

[root@flowerhorn ~]# cat /proc/meminfo

MemTotal = Total memory (it is 1 GB)

Older Xeon processor is 32-bit. The latest one is 64-bit. I heard that AMD's Opteron is superior in benchmark of 64-bit CPU. If I need one more server, I will opt for Opteron. To take advantage of 64-bit CPU, one should install 64-bit OS and applications if they are available. That's what I did. I did install Mandriva 64-bit and Slamd64.

Come on guys. Take advantage. That's the key point here. :)
