Subject: [PATCH 7/7] core.fsyncmethod: performance tests for add and stash
Date: Tue, 15 Mar 2022 21:30:59 +0000	[thread overview]
Message-ID: <876741f1ef9a5b8af28f73948a3e9ddc16d88c6d.1647379859.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1134.git.1647379859.gitgitgadget@gmail.com>

From: Neeraj Singh <neerajsi@microsoft.com>

Add basic performance tests for "git add" and "git stash" of a lot of
new objects with various fsync settings. This shows the benefit of batch
mode relative to an ordinary stash command.
