From 1cbda46d4aae5ba9bd89a1837f0d81a29653ed7b Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Tue, 10 Nov 2020 22:56:38 +0100 Subject: publish: Increase TCP buffer size when sending non-cached nars. This increases throughput tenfold (!) on localhost when downloading large nars without '--cache'. This is a followup to 5e3d169945935b53325e6b738a307ba286751259.
