I think my question will contribute to OP´s post.

I just flashed my N900, smooth sailing all the way, took less than 15 minutes.

I was now searching for a way to make it a bit faster, and found 2 different start points.

One is this (http://talk.maemo.org/showthread.php?t=73315), and the other is swappolube, which as I understand is a script that does something somewhat similar.

I would need some more reference since I don´t fully understand what to do. Thanx!
