Subject: [PATCH v1 00/23] reduce overhead during live migration
Date: Thu, 29 Oct 2020 18:19:40 +0100	[thread overview]
Message-ID: <20201029172004.17219-1-olaf@aepfle.de> (raw)

The current live migration code can easily saturate an 1Gb link.
There is still room for improvement with faster network connections.
Even with this series reviewed and applied.
See description of patch #6.
