@karan
I,m trying to install your patch but i"m stuck in this line:cp /home/user/.bashrc /home/user/.ashrc : no such file or directory
i should make the folder or ignore folder path

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

i get this message with this "/etc/rc.local # Exicuting rc.local"

mount: mounting cgroup on /dev/cgroup/cpu failed: Device or resource busy
mkdir: cannot create directory '/dev/cgroup/cpu/user': File exists


still smooth and responsive brilliant :)

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

Ive had the same error since that step was added, not sure its important.


-----

thanks again karam, will update in the morning,

is there a deb coming soon?

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

i'm doing some test on the patch i can say it,s working really really well,i stress the cpu to see if it will still be responsive but no trouble at all still fluid and smooth, great work karam:):)

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

lol


p.s it's karam :D

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

ok lol:D:D i will correct it

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

@augustthe,F2thaK,eefo
for the .bashrc problem
it is not important for most n900

looks like you are having a problem with bash
i can't tell what is it
anyway thank you for your support :)

And F2thaK
the deb file with a gui should have been released yesterday
as i asked misiak to make it for me
(cause i'm very very busy these days) probably until 1 year i would have free time :) )
But i lost connection to misiak
(he didn't get to internet 1 weak ago and i'm trying to contact him)

The time will tell :)

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

Oh i forgot about this
well this is no problem as rc.local is executed twice so it will say so
no problem with this at all :)

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

this line worked for me this time

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

I have this message:
cp cgroup_patch /home/user/
cp: 'cgroup_patch' and '/home/user/cgroup_patch' are the same file
I guess it's not important but well...

Otherwise no error except the same as in #249

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

i had the same error but what it states , giving the solution :D
you already have that file in required place , so no worries :P

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

Thank you, then everything's fine!

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

how come i really can't install the bash. there was a problem with account-plugin-salut and telepathy-extras. hope someone can help me.

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

Interesting error by me ;)

tee: /usr/local/sbin/cgroup_clean: No such file or directory
tee: /usr/local/sbin/cgroup_clean: No such file or directory^C

Making [/usr/local/sbin/cgroup_clean] executable

chmod: /usr/local/sbin/cgroup_clean: No such file or directory
DONE. The patch has been applied. Restart your computer...
Nokia-N900:~#

Any ideas ;) I have all requirements for the patch :)

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

o well this problem is really strange (it should not happen)
probably you are not doing every thing at root

as the patch should create all the required files (cause they are only text files)
so this problem doesn't make any sense actually
check your steps again and reply me :)

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

Karam, had to flash to was going through your instructions. Instead of reboot after blacklisting the battery module, it can be unloaded by following command without rebooting

modprobe -r bq27x00_battery

Please add the same to your instructions.

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

i had the same problems. and i guarantee i do all the necessary steps.

=======
just found out the sbin wasn't inside the /usr/local/

any alternative?

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

this also works (i use it to load and unload joikuspot module)

anyway i said a reboot is important
for the kernel it self not for the battery module
and also some unexpected reboots may happen if done modprobe

it is not wrong although ;)
but i don't recommend doing that

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

hmm well i didn't think that the not exestence of sbin will take effect
(for me it was created auto using the old aircrack-ng)

so you can try

sudo gainroot
mkdir /usr/local/sbin

then reapply the patch


and pls tell me what happenes with you :)


EDIT : IF this problem is solved with by creating the sbin folder
i will add it to the first post
If not then the problem is with your N900 (or something else)

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

patch worked!!!!

rebooting and waiting for effect.


==============
there are still no effect. Maybe i didn't do much multitasking ?
any move to test between the before and after?

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

how will i know if it worked?

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

can any one post a video here step by step ?please ,will be helpful .
other than this ,for a noob ,its like chinese characters . -REQUEST-
and yeah after installing CSSU,i dont know it felt me like something just happened to my N900 ,it is running like SSU-ultimate -AERO ( fastest car of the world -do u mind ? ) ;p;)

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

well yes
if you use a lot multitasking like a lot of web pages
you will notice a better performance (actually much better)

and as i remember there was a member said that he used to use nokia panorama app
normaly(with out the patch) it lags the hell out of his n900
but after using it
his n900 got more responsive

and did the patch worked after creating sbin?
or not ?

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

@prankster

the steps are really simple just download the patch
and copy then paste the instructions in the terminal

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

New update
just to create /usr/local/sbin

That solves the patch problem of not getting perfectly work

EDIT : For people that applied the patch and worked with them

then ignore this update

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

i am getting this error msg:

mount: mounting cgroup on /dev/cgroup/cpu failed: Device or resource busy
mkdir: can't create directory '/dev/cgroup/cpu/user': File exists

anyone else have the same issue? thx in advance

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

i thought why not made an app which gathering this script (To Speed UP N900) and the script "dbus-scripts and pkill -STOP": http://talk.maemo.org/showthread.php?t=73038&page=2

one .deb will be better for many people.

thank

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

did you forgot to key in the command as root?

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

Error message would be different (something related to permission denied) if it was due to Root access

The second error suggests that the folder has already been created, was this executed twice?

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

karam can u make an app out of it ? a simple deb file if that is possible .
i think many of us will be obliged with that.what say ?

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

Hi All,

I've tried just about every performance/battery/"smoothness" patch available over the last 12 months, including :-
- power kernel scaling (250<>805) with vdd1+2
- powervr.ini
- swappolube/IO tuning
- swap on class 10 SD
- "raid" emmc+sd swapfiles
- reduced desktops (1)
- disabled watchdogs
- simplified (i.e. no) transitions
- un-niced xorg
- disabled xorg access control

I've just installed the "cgroup" automatic process grouping patch on top of all these, and even with all the above enabled the patch makes a really noticeable difference to how rapidly the device responds to input, renders web pages, switches tasks, pretty much everything except heavy IO.

To take this patch forward, I think this change belongs in the kernel, rather than a bunch of shell scripts in userland.

It's been implemented in the mainline linux kernels since 2.6.38 (march 2011) see http://kernelnewbies.org/Linux_2_6_38.

Ideally we'd need a diff against 2.6.28 that incorporates the automatic process grouping changes from 2.6.38 and submit it to pali for consideration in kernel-power48.

Over to, er someone, to create the diff. I'll have a go at it myself, but you might be waiting a long time, so I hope someone beats me to it.

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

Mmmmhm, I see it's tweakable to a fair degree, but the main result automatic process grouping brings is the grouping itself which works well with the kernel's CFS scheduler. Tweaking resource allocation per group will doubtless be worth doing though.

One thing - the rt.period/runtime and memory limit settings do take effect, but these lines :-
echo "512" > /dev/cgroup/cpu/cpu.shares
echo "512" > /dev/cgroup/cpu/desktop/cpu.shares
echo "512" > /dev/cgroup/cpu/applications/cpu.shares
If you cat those settings after modifying them, they've reverted to their old values (1024, 6144, 2048 respectively).

As for notify on release, those are supposed to clean up old cgroups when the last process in the group dies - probably not that necessary on the n900 as we generally don't have users logging in/out that often.

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

From what I can figure out, the secret sauce is that instead of CFS enumerating 150-200 processes to decide who gets resources, it instead enumerates just 3-4 cgroups, reducing the scheduling load by a factor of 50.

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

Un-nice - remove the "-n -8" from dsmetool when xorg runs. It doesn't really have any performance benefit, but by putting xorg back in the mix with all other tasks, it does at least cause the CPU scaling to drop to minimum more often, so it saves some power.

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

Looks like i missed a lot of posts here

ok
1-) FOR the values provided by epitaph

i think just like thingonaspring those values are the most teweakable

echo "555555" > /dev/cgroup/cpu/cpu.rt_runtime_us
echo "600000" > /dev/cgroup/cpu/cpu.rt_period_us
echo "95M" > /dev/cgroup/cpu/user/memory.limit_in_bytes
echo "555555" > /dev/cgroup/cpu/user/cpu.rt_runtime_us
echo "600000" > /dev/cgroup/cpu/user/cpu.rt_period_us
echo "25M" > /dev/cgroup/cpu/desktop/memory.limit_in_bytes

although haven't tested them (and will not be able to until next year) :(

2-) for the deb
Mmm i think it will take a long time to get done (im extreamly busy these days) and i also asked for misiak to make it (with a gui for me) but he is lost these days (never goes online) idk why

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

Hi Karam and others. I installed this patch twice now (first removed old installation and then tested without the patch and then reinstalled the patch). I did not see any noticable difference. It is quite confusing as some report a huge difference. Just wanted to share this.

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

it makes a big difference when stressing the CPU of the device

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

I understand this and when I test this. I do not see any difference.

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

isnt just CSSU maemo15 is enough for a speedy-est N900 ?i wish if there was a patch for battery life enhancement or less cpu usage.in both cases power consumption would be less and N900 will be JF-17.

Re: [ANNOUNCE] Script + Tweaks To Speed UP N900
 

Youre not stressing it enough.


Enabling SMart Reflex is by far the best way to increase battery life
