Subject: [PATCH 16/21] sharedkv: do not set cache_size by default
Date: Sun, 31 Jan 2021 22:28:28 -1000	[thread overview]
Message-ID: <20210201082833.3293-17-e@80x24.org> (raw)
In-Reply-To: <20210201082833.3293-1-e@80x24.org>

These DBs will probably be too small to be worth increasing the
cache size of.
