Subject: [PATCH v2 01/10] migration: Increase default number of multifd channels to 16
Date: Wed, 18 Dec 2019 03:01:10 +0100	[thread overview]
Message-ID: <20191218020119.3776-2-quintela@redhat.com> (raw)
In-Reply-To: <20191218020119.3776-1-quintela@redhat.com>

We can scale much better with 16, so we can scale to higher numbers.
