The "bug" is in the default tuning parameters released for RH9. The suggested fix is to run: /sbin/sysctl -w vm.bdflush="30 500 0 0 2560 15360 60 20 0" And if that makes your system more responsive, then put: vm.bdflush="30 500 0 0 2560 15360 60 20 0" in /etc/sysctl.conf I stress tested my home system and this did make it more responsive - though it wasn't a dramatic difference.
