Just an fyi ... I am not sure what has caused it as all I have seen is a number of commits from Bert that said they were eliminating SQLite queries, but the performance test results have been showing the times for checkout and update to be getting slower. For example on the relatively lightweight test that uses our Subversion tree the time for checkout and update on Windows has gone like this:
Checkout Update 1.7.0 r1085344 0:23.432 0:23.681 1.7.0 r1088721 0:33.175 0:23.681 1.7.0 r1089890 0:42.526 0:35.396 1.7.0 r1085031 0:24.164 0:20.039 1.7.0 r1088319 0:18.782 0:14.172 1.7.0 r1090787 0:27.627 0:25.951 The first three are from my machine, the second three are from Stefan King's. Given the overlap in the builds we used I would look at what happened between -r1088721:1088319 -- Thanks Mark Phippard http://markphip.blogspot.com/
