If you are really adventurous and don't care about the data on your root
fs use the following mount options:
logbsize=256k,delaylog,nobarrier
Personally i would only enable "nobarrier" on Server-Class hardware with
Battery Backup and proper UPS. But since you are using RAID-0 i suppose
you really don't care that much about the data on your root fs.
Note that both logbsize and delaylog will only have effect on your root
fs if added to grub.conf (real_rootflags=) since remounting won't
activate them. Use "cat /proc/mounts" to see if these options were
really enabled.
hth,
Michael
