Can you check your debugger log? If C::B constantly writes messages there, it can easily slow everything by the factor of 10.
checked this ... nothing is being written to the debugger log window ...
I'm going to setup a private SVN repository (with anonymous read-only access) and sync it with the main C::B repository using SVK (http://svk.elixus.org/).
aaaargh ... WinCVS, TortoiseCVS, SVN, VCS and now SVK, what else do we need ? do we need them really ? couldn't we stay with ordinary cvs ?
