You really had better research that a bit more. You are apparently
suffering from belief in a widely disseminated myth (caused by an
incorrect answer remaining in the comp.unix.questions FAQ since 1992,
perhaps because my colleague Ted Timar, who maintained that FAQ, was not
a huge fan of SCCS). SCCS is not necessarily slower than RCS -- and RCS
_is_ still slower than SCCS in many cases, esp. if you use one of the
more modern SCCS implementations, such as Larry McVoy's BitSCCS, or Ross
Ridge's MySC, or even the GNU CSSC.
A common misconception is that SCCS baselines the initial version and
keeps deltas to create newer versions. Actually, SCCS interleaves
all the versions; this is not as bad as the common misconception, but
it _can_ make new development get progressively slower.
Note though that if you don't use the head of the trunk for development
then RCS can degrade rather nastily....
In other words you'd better benchmark before you decide on that
assumption alone.
BTW, what the heck are you doing with putting any kind of repository on
an NFS partition!?!?!?!?

The current maintainer of CSSC is overly careful. I've been using it
happily for years, even on occasion interoperating with it and SunOS-4.

Well, there could be benefits there, I grant you that!
