Mercurial is more than 10 times as bandwidth efficient and considerably more I/O efficient. On the server side, rsync uses about twice as much CPU time as the Mercurial server and has about 10 times the I/O and pagecache footprint as well. Mercurial is also much smarter than rsync at determining what outstanding changesets exist. Here's an empty pull as a demonstration: $ time hg merge hg://selenic.com/linux-hg/ retrieving changegroup real 0m0.363s user 0m0.083s sys 0m0.007s That's a single http request and a one line response.So, what about comparing it with something comparable, say git pull over HTTP? :-)..because I get a headache every time I try to figure out how to use git? :-P Seriously, have a pointer to how this works?
Either you use cogito and just pass cg-clone an HTTP URL (to the git repository as in the case of rsync - http://www.kernel.org/pub/scm/cogito/cogito.git should work), or you invoke git-http-pull directly (passing it desired commit ID of the remote HEAD you want to fetch, and the URL; see Documentation/git-http-pull.txt). -- Petr "Pasky" Baudis Stuff: http://pasky.or.cz/ C++: an octopus made by nailing extra legs onto a dog. -- Steve Taylor
