I think there are actually several tools calling themselves svn2git. There was a C tool once upon a time, but it looks fairly inactive, and the top search hit for svn2git does turn up a git-svn wrapper. Like I said, I am not very up on the current state of affairs.

I'd worry there are other cases where it does impact performance (e.g., perhaps smaller blobs), but I don't know enough about the git-svn internals to say much more.
