Subject: [PATCH 4/4] t/perf: add fsmonitor perf test for git diff
Date: Sat, 17 Oct 2020 21:04:36 +0000 [thread overview]
Message-ID: <0613b07676e8abd0b4f342784b94d11174981537.1602968677.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.756.git.1602968677.gitgitgadget@gmail.com>
From: Nipunn Koorapati <nipunn@dropbox.com>
Results for the git-diff fsmonitor optimization
in patch in the parent-rev (using a 400k file repo to test)
As you can see here - git diff with fsmonitor running is
significantly better with this patch series (80% faster on my
workload)!
