I don't know. There are a variety linked at
http://lbs.sourceforge.net/, and I suspect anything material would be
informative. If in doubt, I'd find a kernel subsystem that is
particularly semaphore-heavy, then find a benchmark for that
subsystem.

Sure, no one suggesting delaying the reposting of this sample code.
However, the subsequent performance question is entirely predictable,
and one might as well prepare for it.
