Karanbir, can you please, in short, explain to me current status of 64-bit CentOS compared to i386? Is it's maturity same as of i386? I started to actively use CentOS when 4.2 was last version. My decision to use i386-only was based on issues with some (or many?) drivers like madwifi for AR5007, it's unavailability for older PC's, my impression in that time was that it was not stable enough, and the main thing was since I decided to create my own mirror of main and third party repositories for internal use, I went with i386. What is actual gain in using X86_64? Performance in %? Main advantages beside performance? The real question is, does it pay off to spend 20-30 GB of HDD space for X86_64 if i386 does the job nicely? Just a sentence or two would be most appreciated. Karanbir Singh wrote: > Mathew S.
