I'm not the most appropriate to respond to you, but I think "Slackware " would not make available on its site, something that would compromise their reputation.

Anyway, wait for the answers .... Mostly for technical reasons ...:-)

If the server has more than 3GB RAM, then being able to use all of it will obviously be good for performance.

The only reason to consider a 32-bit distro is that it makes it easier to run software that's only available in 32-bit. I can't think of any software of that description that you would need for a server.

Thumbs up

Why not run both 32 and 64 bit its not complicated (much) I do, my main install was 64 bit I then added 32 bit support so far everything is fine, googleearth was my main reason for wanting 32 bit capabilities and lives just fine with the rest of the 64 bit libs.

I too wondered about this for some time, but by the time 13.1 came out I was keen to get it working. I loaded the 64bit version onto my laptop and immediately used alienBOB's multi-lib guide to get 32bit working as well. I'm very happy with it so-far. Then at work I took the plunge and installed 64bit on a Nehalem machine - no complaints at all. I'm not sure whether you get any real performance boost - I've read reports of up to 20% speed increase on same hardware comparing identical kernels in 32bit and 64bit mode. But I've not been able to confirm this statistically (or by benchmark), altho' my laptop does feel snappier. My advice .... go for it !

I've found that using 64-bit will always boost performance, but much more so with more than 4GB of RAM, or even with 4GB of RAM.

I don't know if it's something like placebo effect, but I think there is a slightly improvement in performance with x86_64. If this is a server, and all you need is compiled for 64bit, there is now particular reason to run 32bit, in my opinion.

If everything works, don't change it. So, stick to 32-bit until next major update of your system.
