Status so far:

N900 is:
More responsive and faster in some parts
Swap is greatly reduced, using less then 75MB


But, some of my encoded video's really need abit more speed since they are encoded pretty heavily and i am sorry to ask again but have anybody been able to overclock successful using thumb

when i get the time i will flash my other N900 and put every program and IM and such on it like this and compare memory.
