Subject: [PATCH 0/1 v2] Patch to adjust coroutine pool size adaptively
Date: Tue, 11 Jan 2022 18:19:49 +0900 [thread overview]
Message-ID: <20220111091950.840-1-hnarukaw@yahoo-corp.jp> (raw)
Resending patch with fixing atomic access method to use qatomic_read().
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?
