Of course, if your encoder and decoder are fast enough, then the network is worth worrying about. But the top 3 had similar ratios. If network really is the issue, then lz4, Zhuff and some of the others come back into the game.
Of course, then the thing to do would be to sort on the min of the network throughput, the encoding speed, and the decoding speed. That's going to depend on your network of course. Don
