It's the "kernel swap daemon". Handles swapping to a pagefile (in this case, ramzswap)
If you want to disable swap (uses 256MB of RAM, IIRC), look up how to disable ramzswap on Harmattan.
1GB is more than enough for most users on Harmattan.

1GB would normally be enough for a phone, but only 768MB of memory's really "free" on a stock Harmattan install.
Around 500MB's taken up by the system and various libraries over time, leaving only 256MB of fast RAM left.
ramzswap is neat - it allows you to have about 1.2GB total RAM, but CPU usage is high, and speeds aren't nearly as fast as without it, especially if you don't get to that much usage.
so for my usage, I simply leave ramzswap off.

Hmmm.. I have normal mode with (Coderus aegis-install + opensudo) and I tried to disable it with:
It's took a few MINUTES to finish ! Why ?
I opened another terminal window with "top" and saw that /sbin/swapoff /dev/ramzswap0 process takes around 96-98% cpu
It's finished and all looks ok (for now)
Thanks
PS. after reboot it switched again to ON ?
PS2. weird, but now it again show me this process ([kswapd0]) in top for a few minutes, but now it takes around 3.7%
It not should be completely disabled ?

@Schturmann,
You only disabled swap until the next reboot. So after rebooting it should be ON again. If it's using less CPU it's because less swap is being used.

Today I noticed that my phone a little buggy (phone almost not responsive). I checked "top" and I saw process named [kswapd0] takes around 40-70% of CPU. Opened app at this time:
1. One window of default browser with twitter site
2. TranslateALL
3. Documents
4. One PDF file
5. Terminal with "top" running.
Could someone explain me what this process, what he do and why it take so much cpu ?
Thanks
