I looked in you script and understand that infact this should be present in rc.local, so I add it manually.

mkdir -p /dev/cgroup/cpu
mount -t cgroup cgroup /dev/cgroup/cpu -o cpu
mkdir -m 0777 /dev/cgroup/cpu/user
echo "/usr/local/sbin/cgroup_clean" > /dev/cgroup/cpu/release_agent

A lot of you must have heard about the 200 lines to speed up linux while blackhat announced 4 lines to do that
anyway neither of the available tutorials on internel are working on N900

BUT For Fortunately i was able to apply it to Maemo 5 on N900!!!!!

You will notice a lot of improvements in hildon-desktop
ex: faster multitask , faster contacts scrolling , faster images scroling
and basically every thing will be improved
Now the script is not made by me
all what i did is modified it a bit to work on maemo 5
BTW : it is recommended to use good transitions.ini although it is optional to use
Download the patch.tar.gz from attachment it contains the patch and the transitions
place it in MyDocs
Then enter CODE :

sudo gainroot

apt-get install bash
tar xzvf /home/user/MyDocs/patch.tar.gz
cp cgroup_patch /home/user/
cp speedpatch /etc/event.d/
chmod +rwx /home/user/cgroup_patch
/home/user/cgroup_patch
chmod +rwx /etc/rc.local
chmod +rwx /usr/local/sbin/cgroup_clean
chmod +rwx /etc/event.d/speedpatch
/etc/rc.local

DONE

And For transitions file (OPTIONAL)
if you are using the stock themes

cp /home/user/MyDocs/transitions.ini /usr/share/hildon-desktop/

if not then replace /usr/share/hildon-desktop with the path of your theme so in my case (using the blue sky theme)

cp /home/user/MyDocs/transitions.ini /usr/share/themes/Blue-sky/

DONE

NOTE: the transistions file has [thp tweaks] section in the end of it
Also parallax and zoom_on_press under [home] section
So you can use it with CSSU

You may not feel changes until reboot
But probably you will feel before as it happened with me

Enjoy
Please give feedbacks

LAST NOTE:
If you didn't think the patch worked or did anything don't worry it will not affect anything else

JUST to make sure no problems occure when all done
open a terminal window and type:

(As user)

bash

Then exit

(As root)

bash

Then exit
No Problem if you get some errors about files and directories

TO Reverse: ( To Delete The Patch ):

rm /etcr/c.local.backup.txt
rm /etc/rc.local
rm /etc/event.d/speedpatch

And then reboot


And For the people who wants to know what does this script do:

It can feel like speed up, but this has some bad consequences.

but my script gathers about 3 ways so there is no chance that at least 1 of them to work on n900

first i have been using it for about 4 months and nothing wrong with syspart (as it doesn't use effect in it)

second this patch is not published for maemo5 only
it is actualy interigated in the newest linux-kernels
ex: latest ubunu has the patch applied in it
probably pr1.4 will does too
so make sure of what are you saying

regards
