RAID 5 or RAID 0 for Squid proxy
Hi, I have a Squid proxy on a machine with around 6 disks in a RAID 5 array. I moved it on to a new server that had 2 large scsi disks in a RAID 0 array. However, despite the server being an Intel P4 Xeon with 2GB ram, and the old one was a P2 300 with 512MB ram, the new server ran noticably slower - or rather the response time to serve the clients was much slower. All config files for squid were just copied over, so no change there.
Do I have a problem with this new box or is a RAID 5 array really that much quicker? I actually though RAID 0 was quicker as it writes to 2 disks at the same time but can read from either.
The only other thing (and it is pretty major) it went from SuSE 8.2 to SuSE 9.2.
