SVNKit is very slow when listing all properties on repository.

For repository generated by gen-large-svn.py (1 mln paths)

$ time svn proplist -R -r 1001 file:///home/czawadka/repos/large-svn/large-svn@1001
real    0m23.147s
user    0m18.781s
sys     0m4.275s

$ time jsvn proplist -R -r 1001 file:///home/czawadka/repos/large-svn/large-svn@1001
real    61m52.926s
user    59m14.678s
sys     3m6.295s

That means SVNKit (jsvn) is 400x slower then the native (svn) implementation.

SVNKit is aware of that fact as it prepared FAQ how to deal with slow proplist - https://web.archive.org/web/20140923170354/http://wiki.svnkit.com/SVNKit_FAQ#Q:_Recursive_repository_properties_fetch.2BAFw-list_operation_is_slow._Is_it_possible_to_make_it_work_faster.3F

Workaround

To overcome the issue Native Subversion Client should be configured in Fisheye/Crucible.
