[asterisk-users] Is Centos 64 bit or 32 bit better?

[Zhang Shukun]

hi, all
        after a long time development, i need to deploy a production system.

i want to install latest Asterisk 1.6.2.9 on Centos 5.4 . one thing confused me.

my computer hardware support 64 bit OS.

my question is : should i use Centos 5.4 64bit or  Centos 5.4 32bit?

which is better for my asterisk ? consider compatibilityand stability.

this is a new machine , only used for asterisk, no other apps.

Thank you in advance!
