Multithreaded library for image encoding. There are six workloads for PNG and JPG files at quality levels of 80, 90 and 100. It looks like in the chart below that the second half is the quality level 100 runs and the first half is the 80/90 runs.
Topdown profile has an extended duration, perhaps because of extra time to settle down. Again the first parts look like quality level of 80 or 90 and the last part has a different profile.
AMD metrics show we spend approximately two cores. This has some floating point and some L2 misses but not as much as other codes.
