Table VI. Encoding Run Times for Equal PSNR_{YUV}, HEVC vs. VP9 (in %): 735.2

I.e., HM is over 7x slower than VP9's slowest settings. VP9 speeds have improved dramatically since then, and it is now being used real-time (Google is working on adding it to WebRTC), while still demonstrating significant quality improvements over prior generations.

HM is basically a tech demo. It's not meant to be a production encoder.
