2.4.10 seems to behave worse than kernels up to 2.4.9 and 2.4.9ac12 (haven't tried above) with the following workload (everything is only a subjective impression as a user; I don't look at how long the "rm" and the "tar" take because that's not very important for me):
FVWM with 6 open xterms is running XMMS is running
mv linux linux.old nice rm -rf linux.old & tar xzf linux-2.4.10.tar.gz & lynx ftp://ftp.kernel.org/pub/linux/kernel/testing
up to 2.4.9 and 2.4.9ac12: everything works fine
2.4.10: interactive use of the machine is very bad, I can't type a command in another xterm
2.4.10 + 00_vm-tweaks-1: interactive use of the machine works all right, but XMMS does sometimes stutter
This is on a K6 with 300 Mhz. free in 2.4.10 + 00_vm-tweaks-1 gives the following output:
$ free total used free shared buffers cached Mem: 62252 60400 1852 0 2408 32792 -/+ buffers/cache: 25200 37052 Swap: 947824 10264 937560 $
My impression is that there's a problem when several processes do heavy non-cachable disk IO.
