Subject: p7300: add performance tests for clean
X-Git-Tag: v2.6.0-rc0~112^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f49a5650ab536a31a22c2b48398e0e29bb59269f;p=thirdparty%2Fgit.git

p7300: add performance tests for clean

The tests are run in dry-run mode to avoid having to restore the test
directories for each timed iteration. Using dry-run is an acceptable
compromise since we are mostly interested in the initial computation
of what to clean and not so much in the cleaning it self.
