Looking to optimized Linux Mint14, AMD 1100t, 32G, Radeon 7870, OCZ Vertex 256, HDD's. I think I need to look at configuring the scheduler and something else... can't remember lol. Anyway am I backing myself in the corner with these configurations or missing something here? Appreciate your insights or thoughts.

I turned off journaling, and set the FS to be checked at regular intervals.
$ sudo mke2fs -t ext4 -O ^has_journal /dev/sda1
$ sudo tune2fs -o journal_data_writeback /dev/sda1
$ sudo tune2fs -m 5 /dev/sda1
$ sudo tune2fs /dev/sda1 -i 7d
$ sudo tune2fs /dev/sda1 -c 15
$ sudo tune2fs -l /dev/sda1

Also set swappiness=5 since I got 32G ram and mounted /tmp and /var/logs into RAM so they get deleted on every reboot or shutdown.
echo "vm/swappiness=5" >> /etc/sysctl.conf

UUID=522567a9-0f7d-475c-b495-661dc5569599 / ext4  data=writeback,noatime,discard 0 1
tmpfs        /tmp        tmpfs   noatime,nodev,nosuid,noexec,mode=1777   0       0
tmpfs        /var/log    tmpfs   defaults,noatime,mode=0755              0       0

Set FF to use memory for cache
