OpenBSD is not a tickless kernel. If you need nanosleep precision that's much higher than what you're seeing, then OpenBSD is not currently able to meet your requirements. Would it be better to be tickless? Sure, but no one has sat down and figured out how to do that _and_ continue to support the range of hardware we support. Is it on peoples' lists? Sure, but so is a lot of other stuff which is higher priority. Some day? Philip Guenther
