I re-ran the performance benchmarks using 1.6.17 and 1.7.0-beta3.
Server is running 1.7.0-beta3 and running on Solaris x86 VM with 1 GB RAM

You can see the results in this spreadsheet:
I highlighted in green the areas where SVN 1.7 is significantly faster (most
There are a couple areas in red where 1.6 is significantly faster. This is
on the test where there are about 4-5K icons in a single folder.
Checkout/commit with 1.7 are slower but other areas are faster. FWIW,
until 1.6.17 this was about 5x slower in 1.6. We backported a bugfix from
1.7 to 1.6.17 that apparently has even more impact in 1.6 than it did in
