Faster than Perforce!!
Perforce is the fastest SCM on the market. Or at least it was... We made a couple of performance tests last Friday with very good results for our system.
We tested with a 183Mb repository containing 2426 items on it.
Our system stores revisions for both files and directories.
Plastic (our SCM) needed about 52 seconds to perform a forced update (everything gets copied) while Perforce took 58 seconds to do the same.
We took times repeteadly, with almost identical results (a difference of one second between measures).
By the way Perforce is still the fastest, because we are only able to beat it doing updates... Adding files it is much much faster, and checking in and out too. But we are getting closer... :-P
