I see things all over the Internet saying git is fast. I'm currently struggling with poor svn performance and poor attitude of svn developers, so I'd like to consider switching to git. A quick question first.
The core of the performance problem I'm facing is the need to "walk the tree" for many thousand files. Every time I do "svn update" or "svn status" the svn client must stat every file to check for local modifications (a coffee cup or a beer worth of stats). In essence, this is unavoidable if there is no mechanism to constantly monitor filesystem activity during normal operations. Analogous to filesystem journaling.
So - I didn't see anything out there saying "git is fast because it uses inotify" or anything like that. Perhaps git would not help me at all? Because git still needs to stat all the files in the tree?
