The patch causes GET responses to stop reading svn:date from disk so that saves 8 system calls per request: open/fstat/read/close on the revprop manifest followed by open/fstat/read/close on the pack file. There are 2232 GET requests in the checkout so that accounts for pratically all the difference. -- Philip Martin WANdisco
