Subject: [PATCH 11/19] httpd: shrink `mean_life' field to `double'
Date: Thu, 15 Dec 2022 20:52:47 +0000	[thread overview]
Message-ID: <20221215205255.27840-12-e@80x24.org> (raw)
In-Reply-To: <20221215205255.27840-1-e@80x24.org>

`long double' is excessive, not necessary, and a waste of RAM
and locality.
