Release 2.3.1
After a report and additional confirming results the use of poll() in the network receive code for TCP and TLS has been removed. This poll() initially gave better results while testing in a docker container on it's loopback interface but when on physical networks it reduced performance to 1/12th, so it had to go.
Thanks to Brian Wellington @nombwelling (Akamai/Nominum) for the initial report and testing, and to Jan Hák (CZ.NIC) for testing and confirming the results.
