Is it possible to scavenge root and old_to_new concurrently?

[Jianxiao Lu]

There are three phases in scavenger.

1. Scavenge root.

2. Scavenge old_to_new objects.

3. Drain out the copy and promotion lists.

Now, step 1  runs on the main thread. And 2 and 3 are packed as a task job and run in parallel (both main and worker thread).

I wonder if it possible to run step 2 on worker thread when running step 1 on main thread.

Thanks.

Yes, I think root processing could be done in parallel to 2) and 3) as well. It just wasn't considered important enough yet (current plan is to use minor MC for production in the future).

Thank you Dominik. Is there any design doc for the new minor-MC? Could you please share it to me?

Sorry, I don't think there is a design doc yet unfortunately.
