From: Elijah Newren Date: Wed, 4 Sep 2019 21:40:48 +0000 (-0700) Subject: t3427: accelerate this test by using fast-export and fast-import X-Git-Tag: v2.24.0-rc0~138^2 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=476998d05bc62b9baaed240da0893ec5d80d676a;p=thirdparty%2Fgit.git t3427: accelerate this test by using fast-export and fast-import fast-export and fast-import can easily handle the simple rewrite that was being done by filter-branch, and should be faster on systems with a slow fork. Measuring the overall time taken for all of t3427 (not just the difference between filter-branch and fast-export/fast-import) shows a speedup of about 5% on Linux and 11% on Mac.
