     72As part of encoding improvements (mostly in #419), we have collected encoding performance statistics for 4 still test pictures using the current crop of codec code (pre-release version 0.13).
     73These encodings are also used when a video encoding is selected as primary encoding, this is done to optimize bandwidth and CPU usage: video encodings require a full frame everytime, so we use still picture encodings for smaller regions and for automatic lossless refresh.

    95101* all tests were performed on an AMD FX-8150 (octa-core 3GHz AMD CPU)
     102* video encodings are not included, and should generally be preferred to the single picture encodings shown here
    96103* this shows both speed in mega pixels per second (higher is better), and compression ratio (lower is better)
    97104* Low quality at low speed doesn't really make much sense, so some values have been omitted
