From 2144f5e310f6d7127e654691f2b42f86eee350b7 Mon Sep 17 00:00:00 2001 From: Michael Tremer Date: Wed, 4 Mar 2020 20:10:07 +0000 Subject: [PATCH] unbound: Only launch one process MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When unbound is running multiple threads, we have observed that queries where sent for each thread. Since no user should have so much DNS traffic that more than one processor core is being saturated, this is a safe change.
