Subject: [PATCH] performance-tests: tests for renamed/copied files in notmuch new
Date: Tue, 2 Apr 2019 09:40:11 -0300 [thread overview]
Message-ID: <20190402124011.16642-1-david@tethera.net> (raw)
In-Reply-To: <587fa8b9dbaa8b8583e83eaa3825e74a24b5ba20.1537284357.git.git@grubix.eu>
Several people have observed that this is surprisingly slow, and we
have a proposal to add tagging into this code path, so we want to make
sure it doesn't imply too much of a performance hit.
