I updated to the latest Beta of TortoiseSVN and it looks to me like they
have changed the default HTTP client to Neon already. So unless you have
specifically made serf the default client in your servers file it is not
likely that this is your problem.

I developed a set of open-source benchmarks to measure Subversion
performance that you can get here:

https://ctf.open.collab.net/sf/sfmain/do/viewProject/projects.csvn

Perhaps you could set up the repository on your server and run the
benchmarks using 1.6 and 1.7 to see what kind of results you see? When I
run the tests I see considerable performance gain with 1.7. The
"FolderTests" are probably the closes tests to your scenario. It will be
easier to focus on any remaining performance issues if we can identify and
measure them in an open and consistent manner so we can see progress and the
impact of different changes.

If these benchmarks do not show the same problems you see on your real code,
then we need to add more benchmarks so that we can capture whatever the
problem is.
