Nah; my system is also 640MB. I haven't had as much trouble with music
skipping - the main test case for me is Mozilla. I guess I should start
playing music and trying to reproduce this. Mozilla is clearly a fairly
substantial contributor to my problems.

sysctl.conf says:
vfs.generic.usermount=1
vm.anonmin=15
vm.execmin=10
Kernel tuning... anything magic in your kernel? I don't think I have
any. My kernel is built with
options DUMMY_NOPS
which I understand should *improve* performance, but I may be correct.
Hmm. I have DEBUG and DIAGNOSTIC compiled in. Perhaps they're more
expensive than I thought?
