Eg: if you're doing 32 concurrent buildworlds and trying to test interactivity - fine, but that's going to result in a lot of KTR stuff. If you can reproduce it using a dd via /dev/null and /dev/random (like another poster did) with nothing else running, then even better. If you can do it without X running, even better. I honestly suggest ignoring benchmarks for now and concentrating on interactivity. Adrian
