This means we no longer have to deal with having bloated SVN working copies around and we get a nice performance increase as well because we don't have to exec the SVN binary and start a new server connection each time. Of course we have to manually manage memory with SVN::Pool whenever we can, and hack around cases where SVN just eats memory despite pools (I blame Perl, too). I would like to keep memory usage as stable as possible during long fetch/commit processes since I still use computers with only 256-512M RAM. commit should always be faster with the SVN library code. The SVN::Delta interface is leaky (or I'm not using it with pools correctly), so I'm forking on every commit, but that doesn't seem to hurt performance too much (at least on normal Unix/Linux systems where fork() is pretty cheap). fetch should be faster in most common cases, but probably not all. fetches will be faster where client/server delta generation is the bottleneck and not bandwidth. Of course, full-files are generated server-side via deltas, too. Full files are always transferred when they're updated, just like git-svnimport and unlike command-line svn. I'm also hacking around memory leaks (see comments) here by using some more forks. I've tested fetch with http://, https://, file://, and svn:// repositories, so we should be reasonably covered in terms of error handling for fetching. Of course, we'll keep plain command-line svn compatibility as a fallback for people running SVN 1.1 (I'm looking into library support for 1.1.x SVN, too). If you want to force command-line SVN usage, set GIT_SVN_NO_LIB=1 in your environment. We also require two simultaneous connections (just like git-svnimport), but this shouldn't be a problem for most servers. Less important commands: show-ignore is slower because it requires repository access, but -r/--revision <num> can be specified. graft-branches may use more memory, but it's a short-term process and is funky-filename-safe.
