You'd have to do some tests to measure the amount of time actually consumed by the progress bar. It may not be that significant. I think anything less than 5% wouldn't really matter. In any case, 1/10 of a second seems like overkill. Once or twice a second should be fine. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/alfs-discuss FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
