Does substing a directory affects the performance creating/reading/updating many small files in the substed volume? (will use svn there) If yes, how serious is the "penalty"?

subst uses native Win32 API DefineDosDevice(), which should not have any noticeable performance penalty.

I use subst'd drives all the time, including with various version controls and builds and have never seen any degradation; I wouldn't worry about it.
