http://subversion.tigris.org/issues/show_bug.cgi?id=4176 If you rebuild 1.7 with the patch in the issue then the working copy operations are much faster. The problem with the patch is that it changes the behaviour of the library so that some applications may not work. The Subversion command line client works in most cases and if you also apply r1336442 then it works in all cases covered by the Subversion regression tests. I don't know whether other applications such as TortoiseSVN, Eclipse, etc. work. -- Philip
