Subject: Re: [PATCH v3 0/4] Reduce lock contention in the NFS client
Date: Tue, 15 Sep 2026 18:29:00 +0000	[thread overview]
Message-ID: <20260915182900.2995708-1-tmenninger@everpuredata.com> (raw)
In-Reply-To: <20260915-performance-v3-0-ae26d460bfd3@kernel.org>

I built and tested v3 on the same 96-CPU dual-socket NFS/RDMA client
where I reproduced the v2 rpciod affinity regression.

With the WQ_AFFN_SMT scope changes removed, I can no longer reproduce
the throughput regression on my workload.

I also reviewed the remaining four patches and found no issues.
