How can I see if I'm using the 32 or 64 bit OS?

[edge]

I've done the perfect install of Fedora RC4 some time, but I'm not sure how perfect it is...

The server is a Dual Xeon system.
In the bios it's showing:

Bus speed: 800 MHz
logical processor: enabled
Sequence memory access: enabled
Demand based power management: disabled
Processor 1 ID
Core speed: 2.80 GHz
Level 2 cache: 2048 KB
64-bit technology: yes (Intel MB64T)

Processor 2 ID
Core speed: 2.80 GHz
Level 2 cache: 2048 KB
64-bit technology: yes (Intel MB64T)


Now how can I see if I've installed the correct kernel/core?
Same thing for ISPconfig. Is there a way to see if I'm using the 64bit version?

btw. uname -m is only showing me: i686/
Is that correct?

This means you have a 32-bit OS. On a 64-bit OS, uname -m would show x86_64.

Than this is no good (I think)... Is there a big advantage of using the 64-bit OS? (it's only a webserver that is doing about 50.000 page views a day)

Also.. Is it possible to change the 32-bit over to 64-bit (only access I have is with SSH). I could (if needed) get the server from the data center, and do a new install, but this would be my last option.

Thank you for that info falko..

** edit **

Looks like I will not update to the 64-bit OS, as my server does also use Coldfusion (a lot), and it looks like Coldfusion does not work on a 64-bit OS :(

There is no advantage when your server does not have more then about 3GB of ram. The disadvantage of the 64Bit linux distributions currently available is that you do not get all software as 64Bit and some 64Bit linux distros does not seemed to be as polished as the 32bit versions.
