Please disregard those conclusions, I misread the ffmpeg results and didn't look at all thread counts for the sysbench runs. Looking more closely, the latest ULE patch improves ffmpeg performance slightly but degrades buildworld performance slightly. As for sysbench, the new patch takes a hit with 4 threads (1 per core), but is better with 8 threads (2 per core). It's slightly better at 12 threads (3 per core) and 16 threads (4 per core).
