While looking through the various 1.10-related topics, I remembered about this issue. I have been able to narrow it down in my environment to https://svn.apache.org/r1778923 (Ensure that even long-lived DAV connections use up-to-date authz.) Perhaps, a simpler reproduction script would be to issue an 'svn log' for a medium-sized repository. In my environment, doing so for the trunk of TortoiseSVN's repository with 25,000 revisions causes the httpd process to consume up to a 1 GB of RAM while processing the request. Overall, the log takes around 11 seconds instead of 2, compared to 1.9.7. Unless I am missing something, this might be worth considering before the 1.10 GA release. Thanks, Evgeny Kotkov
