Hmm... let me think...

I remember a setup wich LOTRO was unplayable due 'lag', but it ended being
related to poor filesystem performance (I think that also NCQ had some impact
performance in that case).

And was solved modifiying /etc/fstab this:

/dev/sda1 /boot     reiserfs   defaults,notail       0 0
/dev/sda3 /         ext3       defaults              0 0
/dev/sda5 /mnt/sda5 xfs        defaults              0 2
/dev/sda6 /mnt/sda6 ext2       defaults              0 2

To this:

/dev/sda1 /boot     reiserfs   defaults,notail       0 0
/dev/sda3 /         ext3       rw,noatime,nodiratime 0 0
/dev/sda5 /mnt/sda5 xfs        rw,noatime,nodiratime 0 2
/dev/sda6 /mnt/sda6 ext2       rw,noatime,nodiratime 0 2

Actually rw,noatime,nodiratime options are safe an deliver between 10%~50% IO
performance boost as the filesystem don't write every time that writes/reads a
file to update the last access time.

It can appear insignificant, but mind on it, just every time a read or write is
performed, atime writes again to hardisk, and harddisk (or flash drives) are
the slowest part on modern PCs if we ignore optical media drives.

Please try and report.
