@EgorBo this is coming from BDNs own codegen changing due to a jit change rather than any of the tests code changing, correct?

Yes, BDN uses volatile to consume [Benchmark]'s return value every iteration: https://github.com/dotnet/BenchmarkDotNet/blob/fd5b76691505d53f3e934f8502629c006539e82c/src/BenchmarkDotNet/Engines/Consumer.cs#L22-L155

@AndyAyersMS pointed me to the fact that all these "regressions" have smaller "overhead invocation" counter:

And presumably final result is "realTime - overhead" and overhead is now smaller here

Thanks!

CC. @adamsitnik as an FYI. This is another case where the benchmark isn't changing, but rather changes to BDN itself or to its codegen produced by the JIT are influencing the result, sometimes significantly.

There is still a puzzle here -- the same consumption sequence should exist in both the overhead delegate and the benchmark delegate, so in principle if both change the same way, the net result (benchmark - overhead) should remain the same. But that doesn't seem to be the case.

cc @timcassell @AndreyAkinshin who introduced some changes to this are of BDN recently

The only codegen change in BDN recently was dotnet/BenchmarkDotNet#2335, which shouldn't have any effect. We know the overhead measurements are currently flawed for non-void benchmarks (dotnet/BenchmarkDotNet#2305).

We don't think it's BDN update's fault (or rather - anyone's fault). It's just that BDN uses volatile writes (those Consume) methods every iteration (or even more than that if a benchmark is unrolled?) which are fairly expensive on arm64 because of explicit memory barriers - my PR relaxed them to be less expensive (even more cheaper on armv8.3+ with LRCPC which the CPU in question does support - ampere) so the overhead metric signifacantly decreased:
image

Many of the benchmarks in ^ list (all of them?) don't use volatile anywhere so the Consume is the only culprit. The question is only in how exactly BDN measures overhead, esp in cases where it decides to unroll benchmark?

The question is only in how exactly BDN measures overhead, esp in cases where it decides to unroll benchmark?

It does exactly the same number of volatile writes in the overhead as it does in the workload (once for each delegate invocation).

    $LoadArguments$
    for (System.Int64 i = 0; i < invokeCount; i++)
    {
        consumer.Consume(overheadDelegate($PassArguments$));@Unroll@
    }
}

private void WorkloadActionUnroll(System.Int64 invokeCount)
{
    $LoadArguments$
    for (System.Int64  i = 0; i < invokeCount; i++)
    {
        consumer.Consume(workloadDelegate($PassArguments$)$ConsumeField$);@Unroll@

So OverheadActual jumps from 6.3390 ns/op to 1.9956 ns/op in my PR (#70794)
WorkloadActual and WorkloadPilot are also better with my PR. Also, when I benchmark it with Stopwatch I am also seeing improvements with my PR as expected.

I think for BDN we migth want to introduce a better way to consume a value similar to Java - "Blackhole" API intrinsified in JIT. I am going to close this one since there is no sign this is a real regression, we may spend some time investigating BDN internals but I'd rather invest into the "Blackhole" API for it, e.g. https://javadoc.io/doc/org.openjdk.jmh/jmh-core/1.23/org/openjdk/jmh/infra/Blackhole.html

I have a PR for that already awaiting review. dotnet/BenchmarkDotNet#2336

"Blackhole" API intrinsified in JIT

That would probably be useful in general.

Nice!! Thanks

Going to put up a proposal once I have a moment!
