I've found that with the latest kernel release (2.4.5) VM performance has
been greatly improved. kswapd and bdflush no longer use 200% of my cpu
cycles when simply doing a dd bs=1024 count=8388608 if=/dev/zero
of=test.file. All of my test systems remain responsive with about 180% cpu
available. These systems are running software RAID and 3ware IDE raid with
2GB of memory and 4GB swap. Have you tried 2.4.5?
