[PATCH 0/1] Patch to adjust coroutine pool size adaptively

Posted by Hiroki Narukawa 2 years, 3 months ago

We encountered random disk IO performance drop since qemu-5.0.0, and this patch fixes it.

Commit message in c740ad92 implied to adjust coroutine pool size adaptively, so I tried to implement this.

Could you review this patch?
