From 737b19b50ccecfea56875472e3377ad989a1659f Mon Sep 17 00:00:00 2001 From: Jeff King Date: Fri, 28 Jun 2019 05:41:35 -0400 Subject: [PATCH] t3311: use test_commit_bulk MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit One of the tests in t3311 creates 300 commits by running "test_commit" in a loop. This requires 900 processes. Instead, we can use test_commit_bulk to do it with only four. This improves the runtime of the script from: Benchmark #1: ./t3311-notes-merge-fanout.sh --root=/var/ram/git-tests Time (mean ± σ): 5.821 s ± 0.691 s [User: 3.146 s, System: 2.782 s] Range (min … max): 4.783 s … 6.841 s 10 runs to: Benchmark #1: ./t3311-notes-merge-fanout.sh --root=/var/ram/git-tests Time (mean ± σ): 1.743 s ± 0.116 s [User: 1.144 s, System: 0.691 s] Range (min … max): 1.629 s … 1.994 s 10 runs for an average speedup of over 70%. Unfortunately we still have to run 300 instances of "git notes add", since the point is to test the fanout that comes from adding notes one by one.
