These tests where run on a Dual 2Ghz G5 running MacOS X 10.4.1 using the stock cvs binary and the svn and svk binaries from the SVN-1.00-2.dmg.
The repositories were always local and being accessed though file://, including cvs.
- svk info actually builds a cache which provides more info about the current working copy like it's merge history, so it's not really equivalent to svn info. This cache is also used to make svk switch safe, in that it won't switch to something that doesn't have a common ancestor with the current wc.

All tests where run on a Dual 2Ghz G5 running MacOS X 10.4 using the stock cvs binary and the svn and svk binaries from the SVN-1.00.dmg.
The repositories were always local and being accessed though file://. The first checkout was also run twice at the start of each series to preheat the buffer cache.
