Two performance notes from the outside world

Here are two specific problem areas I've heard of from a big open
source project:

  * svn log -v on a revision with a huge changed-file list, such as an
    import. It takes a long time to compute the changed-path list,
    and the whole thing gets stored in memory. If we could make this
    streamy, it might improve perceived performance as well as memory
    usage on the server. There may also be inefficiences in the
    calculation of the list, though I haven't looked.

  * I don't think we have a story for maintaining vendor branches (a
    la successive "cvs import" commands) which works for a large tree.
    svn_load_dirs.pl is too slow, and simply importing successive
    versions into different trees gets you no historical association
    between the files.
