From: Jon Simons Date: Fri, 09 Oct 2026 19:29:51 GMT Subject: [PATCH 13/15] t/perf: measure --force-with-lease in p5516 Message-ID: <20261009192953.81794-14-jon@jonsimons.org> In-Reply-To: <20261009192953.81794-1-jon@jonsimons.org> Extend p5516 with rows that push the same delete refspecs plus one explicit --force-with-lease=: per refspec. The new rows are used to demonstrate a speedup in a subsequent commit.
