I had the same issue with Ubuntu 10.10. After installing a kernel from
the upcoming 11.04, doing a 'time /usr | wc -l' went from 3 minutes to 6
seconds. And yes, I dropped my caches. :)

I installed the following image, BTW:
//launchpadlibrarian.net/65900455/linux-image-2.6.38-6-generic_2.6.38-6.34_amd64.deb
