I believe that Linux uses a less precise clock that scales better across cores and is much faster than the precise clock FreeBSD uses even on one core. I don't know POSIX and other standards well enough to know if this is an acceptable solution on FreeBSD. However, there are less precise clocks on FreeBSD that are considerably faster (i.e., the _FAST variants). Someone with more expertise in these matters needs to comment on whether a change to using a _FAST clock is appropriate in libc. If it is acceptable, I think that it is easier to just make time use the FAST clock instead of getting programmers to change their programs.
