Of course: A file:/// commit must be slower than a svn:// commit. If you
think about it you will know why:
the bottleneck is the harddrive. During a commit, the client first has
to diff the whole working copy. Then send that diff to the server. The
server has to receive the diff, and apply that diff to the repository.
All this requires a *lot* of disk access.
With file:/// access, the disk access of the server part is on the same
machine or even the same drive as the client, so the harddrive gets
stressed more. If you however commit via svn://, then the repository
part of the harddrive access happens on a different server.

Even if you have the svnserve running on the same machine where you also
tried the file:/// access: svnserve is a different process. That way the
OS can optimize the two processes with their disk access.
