i think that the default I/O scheduler
should be change from CFQ to deadline
---------------------------------------------------------------------
i have test CFQ and deadline I/O scheduler
on a DELL Latitude 120L with 1GB of RAM and 40GB hard drive
with EXT4 filesystem and GPT with both I/O schedulers
and Found that deadline I/O scheduler is the fastest
--------------------------------------
also tested
EXT3 with MBR and deadline I/O scheduler
EXT3 with GPT and deadline I/O scheduler
EXT4 with MBR and deadline I/O scheduler
EXT4 with GPT and deadline I/O scheduler
-- all are faster with deadline I/O scheduler
ubuntu versions tested - Ubuntu 9.04, Ubuntu 10.04 (LTS), Xubuntu 10.04
--------------------------------------------------------------------
also test both I/O schedulers on two other computers (total of 3 computers)
the deadline I/O scheduler preformed the best/fastest
-----------------------------------------------------------------
also went deadline I/O scheduler is put in Grub ( etc/default/grub OR grub.cfg )
the boot speed is increased and desktop speed
OR went deadline I/O scheduler is put in rc.local ( etc/rc.local )
the desktop speed is increased only
