Subject: [Qemu-devel] [PATCH v2 6/8] multifd: Change default packet size
Date: Wed, 20 Feb 2019 12:56:09 +0100 [thread overview]
Message-ID: <20190220115611.3192-7-quintela@redhat.com> (raw)
In-Reply-To: <20190220115611.3192-1-quintela@redhat.com>
We moved from 64KB to 512KB, as it makes less locking contention
without any downside in testing.
