I don't know if they are loaded on boot. I will look into it once I get some time.

On a slightly different note, I have gone a full day with the settings above without a crash, which is about 3x as long as it went before. The vm.dirty_background_ratio = 55 and vm.vfs_cache_pressure = 20 seem to be the difference maker, so far.

For ultimate NC utility, smoothness and battery life, check out my guide
And be sure and hit "Thanks" if you dig it.

BTW it looks like cycling wifi resets tcp options to defaults.

So what's the word on this. Has anyone written a script for the non-V6 parts? I'm really interested in trying the wifi tweaks. Are they being incorporated into CM 7.2 or Mirage? Do the changes stick or do they need reset? I'm thinking about just trying what mr72 posted but figured I'd ask for updates first.

Ok, I did the first two parts of mr72's modified tweak and seem to be getting better wifi reception and speed. I didn't do the virtual memory part because I don't feel that I need it. My Nook is totally rockin'.
