In this 2603 release, we put lots of effort optimize these areas including codec bitrate algorithms, bandwidth data filter, memory usage, QP setting and TCP socket options; now we can achieve much better performance for lossy network environments and/or long-haul connectivity. Below are some reference benchmarks:
