Windows Jeff Atwood explains why Vista uses so much memory. "You have to stop thinking of system memory as a resource and start thinking of it as a a cache. Just like the level 1 and level 2 cache on your CPU, system memory is yet another type of high-speed cache that sits between your computer and the disk drive. And the most important rule of cache design is that empty cache memory is wasted cache memory. Empty cache isn't doing you any good. It's expensive, high-speed memory sucking down power for zero benefit. The primary mission in the life of every cache is to populate itself as quickly as possible with the data that's most likely to be needed - and to consistently deliver a high 'hit rate' of needed data retrieved from the cache."

I tried adjusting swappiness and FS cache aggressiveness, but I couldn't make linux not lock up for short whiles (annoying e.g. when listening to music).

This isn't 'proven' in any way, but I had issues of this nature on Windows and Linux with intergrated sound cards.

Eventually, the drivers got better, and the problem went away. I still notice a distinct lag between hitting the play/pause key and the music stopping and starting. This problem doesn't seem to occur with Emu10K1 based cards (SB Lives), so my guess is that it's either a problem of a low quality sound card, or badly written drivers.
