Hi Ilya,
The performance that I saw was quite reasonable. True, doing commits in
ClearCase is not as fast as in SVN or CVS, but not a whole lot slower.
ClearCase certainly is overhead without benefit for five engineers. But
for 80 engineers at three geographic locations and multiple product
levels, i.e. shared library level, application level, product level, and
multiple releases with differing toolsets that needed to be saved in
addition to the application code, ClearCase had distinct advantages. You
do need a guru on hand though. Don't try to teach the engineers how it
works or expect them to understand it. Just tell them what to do.

Agreed, but you've also mentioned that developers rarely take the time to
understand ClearCase. In the army, we also tried to implement UCM (the
'multiple development streams + delivering to integration stream' deal) and
it was regarded as overhead without benefits. Then again, ours was a team of
5 developers.
For example, we pretty much gave up on orderly use of UCM activities and
delivering activities separately, since we soon found out UCM activities
easily become inter-dependent and thus not really separable. (Yes, I
understand why they become interdependent -- it makes sense, but it doesn't
mean the UCM model works.)
Jonathan, did you see it work better in a larger setup?
P.S. I'm still standing behind my claim about horrible performance (and we
had decent hardware in the army rollout).
