Excellent idea. Unfortunately, I don't have enough disk space to mirror the whole ASF repository on my laptop- I'll try it when I get back to my desktop (in 15~20 days). In my prelimiary benchmark, I also found that I beat `svnsync` over the same network connection :) > Even better, having the SVN repo and the "exported" git repo on > separate hard disks to minimize I/O as a bottleneck. Unfortunately, a lot of middleware components are missing and we cannot export it to a Git repository just yet- see my previous email about this [1]. Great idea though- will try it in future. > (Great work, by the way.) Thanks, and thanks for the feedback! :) [1]: http://article.gmane.org/gmane.comp.version-control.git/150035 -- Ram
