optimizing CPU utilization rate

Open helloWorld-zy opened this issue 5 years ago • 4 comments

When I encoding a 4K movie, the utilization rate is vary between 12.5% to 87.5%. I got 0.170 fps under --speed 3 and 0.3fps under --speed 8 on my Ryzen 7 1700, and nearly doubled speed on 3700X, it's way too slow. I don't know if it's because AV1 should be this slow, or the optimization.

rav1e parallelizes over tiles pass --tiles 8 or --tiles 16 and it will use more of your hardware.

I got those result when I used --tiles 32. And this is faster than not use it or 8 & 16.

can you please provide information on:

  • how many cores on the machine
  • if the utilization rate is the one read on top or such tool (as in average cpu usage, not core usage)

You may use this alternate cli while I'm working on using more parallelism.

  1. 8C16T
  2. Would you release X64 binaries under Windows, or a guide of how to compile it lol, I don't know how to do that
