Hey Jerome,

Here are the performance changes we see from enabling the new VP9 multithreading. Can you verify that things are as expected?

In particular, PSNR is up ~1dB, but CPU usage is also up a bit.

Added some more alerts to the report linked above.

Encode time is decreased across all tests, as expected.

The increase in PSNR on the Android devices seems to come from the increase in encode_frame_rate, which then also results in some increase in CPU.

A couple of more alerts added to the report.

Some more alerts added.

Added more alerts.

Jerome, if all the changes are expected, feel free to close this bug.

The performance improvements are expected.
