On my box with 128 MB dual SMP 450 MHz box, there's still definitely something broken (pre7-8). I notice it most with mutt loading the linux-kernel folder... The folder is about 54 MB, and it takes kswapd about 3 to 4 seconds of CPU time to clear out old stuff when it loads. This is pretty bad considering mutt itself takes only about 5 seconds of real time to load the folder. The main thing that fills up my cache is mainly playback of MP3s off disk, which is pretty much running all the time. If I open the folder, quit, let MP3 playing fill eat up the free memory into cache, and then run mutt again, kswapd use goes up 3 or 4 seconds further again. I never used to see this with 2.2 kernels...
