I have a server running Centos 4.7 32bit. Will moving from 4Gig of RAM to 8Gig do any good? Since its 32bit I assume it will only be able to address the first 4Gig not? When I installed CentOS I did not do anything special to enable using more then 4Gig if thats required. Exim, spamassassin and Clamd seem to be the biggest load on this machine. My biggest bottle neck is disk I/O anyway. Wish

With the default settings in my Supermicro motherboard CentOS calls my SATA drive /dev/hda. If in bios setup I change 'Native Mode Operation' from auto to 'Serial ATA' it boots up calling the drive /dev/sda. I keep thinking its likely better under /dev/sda not? Any problem switching it to that after install? Matt

On a running 64 bit CentOS 5.6 box is it possible to convert from Ext3 to Ext4 to improve performance? Right now I can deal with a few hours of downtime on it. This is an email server with lots of I/O due to seek time. Software RAID1 as well. Will Ext4 offer much of an improvement?
