@ SavageD, or whomever might know... first off i would like to say a big THANK YOU!!! to SavageD for all your work and experimenting in putting these tweaks together. i took a peak inside your TuneN900.sh script to see how your system tweaks varied from my own. i prefer to hard-code my tweaks directly into my rcS and rcS-late files rather than running a modifying script at start (i don't use Swappolube for this reason). i noticed some interesting discrepancies between your ideal setting and what i thought were ideal setting, and i was wondering if you might be able to shed some light on why you chose the values you did. echo 6 > /proc/sys/vm/page-cluster i currently am running with this value as 3. some believe 1 is a good value while other's argue that the leaving this @ 5 (nokia default) is better. i landed somewhere in the middle and it seems to be working well for me. what effects did you notice while experimenting with this value? echo 900 > /proc/sys/vm/dirty_expire_centisecs echo 900 > /proc/sys/vm/dirty_writeback_centisecs i current have both these values set to 0 (disable). i believe the nokia default was 500 or something in that neighborhood. is it actually beneficial to allow these daemons to run (just less frequently than nokia's default)? echo 40 > /proc/sys/vm/vfs_cache_pressure i had originally left this @ it's default value of 100, but decided to give it a go @ 40. having changed multiple values it's impossible for me to be able to tell what exactly the effects of this are on my system. so i ask you, whom i assume experimented with control tests, how much exactly does this setting effect the devices performance? echo 60 > /proc/sys/vm/dirty_ratio again i cannot remember the default value for this, but i changed mine to 95 after reading about it in a blog a while back. does this value work better after being set lower? i realize setting it too high risks of running the device out of memory, but setting it too low causes unnecessary writes as it starts dumping dirty writes too often. obviously you feel 60 is a good value for this, but i am curious how much testing (and what results) you did before arriving at this conclusion. well i think that's it for now. Thanks again, and keep hacking! http://www.knownokia.ca/2010/08/n900...-and-more.html (original blog post i used for modifying vm setting)
