This might take some time and resources to run, since there's a sync command which writes down to the flash memory.Code:I run a cronjob that drops buffer cache containing pagecache, dentries and inodes, to clear out unused dirty pages (sync; echo 3 > /proc/sys/vm/drop_caches).
Given that we haven't cron by default on our devices, and I don't know how to mess with the alarmd daemon (and I'm not sure I'll ever do), I would then add an icon to run the command and free memory when the user likes to, i.e. when the device isn't going to do critical things like answering a call or shooting a video.
What do you think? Button or alarmd?

Adding my thanks too
But I have noticed that at least some of the parameters do not survive a reboot?! While it seems that it should.

This certainly seems to have speeded things up.
Not rebooted as of yet though.

I'm greedy, and would like to see both! The ability to have a "garbage collector" running automatically would be great.Concerning this issue, I want to implement the small memory-freeing command that Simon describes in his blog post, saying he runs it as a cron job.

Would an good idea be to spin this off and merge with the optimizeN900 thread.
There does seem to be a multitude of different threads each offering different parts of the jigsaw which is N900 optimisation.

while it should be 95
If I launch again the DEB, then the parameters turn to be at the correct values.
PS: some weeks ago I had modified the rcS file and did change the parameters of swappiness and page-cluster directly in the file. Could that be related? (I have serious doubt but...)

I doubt you manually changing the swappiness and page cluster made a difference, as I never have changed them and im getting it. I'd expect everyone would be the same?

@P@t: you're right. Both dirty_ratio and dirty_background_ratio don't get saved. I'm going to try to see why

Would be good to get it to survive a reboot

"swapoff/swapon/swapoff via a temporary swapfile"
Thatīs why I could not swapoff. Stupid me!
