From mboxrd@z Thu Jan 1 00:00:00 1970 From: Michael Tremer To: development@lists.ipfire.org Subject: [PATCH 1/2] unbound: Only launch one process Date: Wed, 04 Mar 2020 21:11:52 +0000 Message-ID: <20200304211153.1842-1-michael.tremer@ipfire.org> MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="===============3892050954600362093==" List-Id: --===============3892050954600362093== Content-Type: text/plain; charset="utf-8" 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.
