well that's a good point
however the last update was on 3 jan

and the creation if speedpatch was a result of testing
perhaps i have no huge expert to explain how it does that
but according to speedpatch testers .. it appeared that it does something

and i wouldn't take a chance a create a new thread (and it was my first thread i ever create) if i wasn't sure that cgroup patch does something
if you have noticed that the first versions were just scripts
not in devel

but after i got many requests uploading it devel .. had to do it

as for battery patch

1. vfs_cache_pressure

you can add
3- renice processes
4- changes minfreq to 720 when a call is received (which will improve the response)
5- uses conservative module (still not proven it's the best)

i think that's why it's called extras-devel ?

well it doesn't require it .. it's just compatible with it
the thing about KP49 is that it made it possible to OC with maxfreq 900mhz with vdd1 enbaled

my older versions had 750 as max with vdd1 enabled
now the are 805mhz with vdd1 with KP49 only
but if the user has an older version
then it will use 750 as max

well here :

in offline mode,device with KP49, underclock profile 125-600 has with vfs 10 and reniced processes

xx>mA with batterypatch than without it
of course the hard ware cannot be edited .. but N900 requires quite less battery life than without batterypatch

in that one overclock profile with conservative module
well got nothing to say about that but tests showed me it improves continues time of using

may i ask you what kind of problem batterypatch may cause ?
ok i got that speedpatch can cause problems (although not with me)

thank you
