You can try it, but depending on a lot of stuff it may not A) work nor B) be a good idea if it does. If you want a faster (but less exact!) gettimeofday, change the call to microtime() to getmicrotime() in the gettimeofday() in kern_time.c -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
