Subject: [PATCH 0/1] commit-graph: avoid unnecessary tag deference when merging
Date: Fri, 20 Mar 2020 21:44:16 -0600 [thread overview]
Message-ID: <cover.1584762087.git.me@ttaylorr.com> (raw)
Hi,
Here's a patch that Peff and I were kicking around from a couple of
months ago when we were investigating deploying commit-graphs at GitHub.
Particularly, we were looking into why merging two commit-graphs after a
write with '--split' took as much time as we were seeing in our
infrastructure.
This patch avoids an unnecessary tag dereference in
'merge_commit_graph()', which can improve the running time of a
commit-graph write by around ~7.4% on average.
Thanks in advance for your review.
