Non-persistent connection performance improvements in 5.6

One of my favorite performance improvements in 5.6 is "faster non-persistent connections". I couldn't find this information from release notes, but non-persistent connection is really faster in 5.6. Here are sysbench micro-benchmark results. I tested from 100 concurrent clients, running remotely. Clients simply connected and disconnected repeatedly. versionconnections per second 5.1.6520712 5.5.28
