r1325896 implies this is most significant for ra_svn. So I compared the testsuite over ra_svn built with the "fast" code and the "slow" code. The CPU used by the testsuite and svnserve was: "fast" code 749.93user 404.98system 9:09.25elapsed testsuite 0:32.43 svnserve 742.84user 400.00system 8:59.75elapsed testsuite 0:32.70 svnserve 739.51user 400.87system 8:58.91elapsed testsuite 0:32.66 svnserve "slow" code 745.06user 402.36system 9:04.21elapsed testsuite 0:32.73 svnserve 739.94user 401.86system 8:57.13elapsed testsuite 0:32.58 svnserve On my Linux box this optimisation isn't significant. Perhaps it makes a difference on some other platform or with some other test scenario, but at the moment it's not clear why we would want with this code. -- uberSVN: Apache Subversion Made Easy http://www.uberSVN.com
