Re: Finally got a real improvement on battery life
 

how do you change page cluster ?

Re: Finally got a real improvement on battery life
 

Any instructions for indexing? Which problems can be expected by disabling it? I mean, which function has the indexing option at all??

Re: Finally got a real improvement on battery life
 

I've been trying swappiness at 30 for the last couple of days and I have to say it is one of the best changes you can make to your N900. It is up there with overclocking for improved experience.
100 is a really stupid default for a device like this.

I haven't touched page cluster because I am not convinced of the reason for changing it.

Re: Finally got a real improvement on battery life
 

When I try swappiness as low as 30 I get stuttering in music player.
Then I tried 60.
This morning my n900 rebooted without external action and got stuck in a reboot loop. I had to reflash rootfs and optfs through backupmenu. And that's it.

It is extremely unlikely that swappiness had anything to do with your problem. It just adjusts when the kernel decides to swap pages to disk. Nothing that would even crash the phone, let alone change anything permanently.
