64bit/32bit Question

Hello

I have a AMD64 HP laptop with 512Mb RAM. It ran ~ok with 64-bit 10.1 until an install went awry and I decided to start again and reinstall. I use 10.0/32 at work and have always been impressed with the performance. The 64bit installation at home though was a little clunky, periodically freezing and not being particularly quick. I decided therefore to install 32 bit 10.1 at home on my 64bit hardware.

So, i've found that my new 32bit install runs very well. Very zippy. Except, the fan comes on a lot more and this has me worried. I checked out the Gnome monitor and the CPU peaks at 100% quite a lot (firefox uses 40% with just some gifs going on). Though if I leave it doing nothing, it will settle to ~3-5% which I guess is about right. Also I can confirm that frequency scaling is working.

The only thing 'bad' that i've noticed is that the screen update seems a bit too quick, and the mouse flickers a bit more, though it doesn't freeze.

Does anyone have any thoughts? Mainly i'm concerned about the processor getting hot and the fan being on a lot more. Should I go back to 64bit?

thanks!
Mike

try adding the "no_timer_check" kernel option, see:
