For what it's worth, when I tried it, the relationship is reversed: [hg]$ time hg clone http://code.python.org/hg/branches/py3k/ ... hg clone http://code.python.org/hg/branches/py3k/ 24.44s user 3.43s system 10% cpu 4:15.48 total [hg]$ du -hsc py3k 105M py3k [svn]$ time svn co http://svn.python.org/projects/python/branches/py3k/ ... svn co http://svn.python.org/projects/python/branches/py3k/ 5.03s user 7.01s system 12% cpu 1:35.97 total [svn]$ du -hsc py3k 131M py3k Mercurial's checkout with the whole history is actually smaller than the SVN checkout because it applies some very nice compression to the history whereas the SVN checkout has an uncompressed copy of every single file tucked away in its .svn/ directory. My mercurial checkout happens to be slower, but I don't know whose fault that is. I'm still using Mercurial 1.5.1 on my OS X box, and while I wasn't doing much that would take up CPU or bandwidth, I wasn't trying especially hard to prevent such interference, either. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
