: The best kernel-internal time representnation is ticks, with a simple : baseline cache mechanism to convert it to other formats (e.g. as : required by NFS, UFS, userland, etc...). Nothing beats ticks... : a binary fixed point format doesn't even come *close* to being better : then straight ticks. : -Matt Before this gets misinterpreted, the 'ticks' I am talking about is not the kernel timer interrupt ticks... it's the high resolution cpu or 825x ticks we get. e.g. frequency dependant on the timer we use. -Matt Matthew Dillon <dillon@backplane.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
