Hight Volatility & Strange4 Disasm #1124

@yahorsi I just want to clarify: do you suspect that BenchmarkDotNet produces incorrect results or do you want to just understand performance difference between different modes? In the second case, it's better to create an issue in https://github.com/dotnet/coreclr/ |
I want to understand the source of the volatility I see in the benchmark. My wild guess is that in the benchmark we compare code that is jitted differently (using different tiers). My wild guess is that issues/volatility is caused by the tiered jit. In general, after thinking about tiered jit I do not see how is that possible to benchmark without all benchmarks being jitted using exactly the same tier/mode. Otherwise it is not apples to apples. Run benchmark once again with sources and il. Here are results , BTW, there is no JOB description here in the dasm that makes it impossible to understand what JOB it belongs to. Note, I have different jobs with same framework moniker but different environment variables .NET Core 2.2.3 (CoreCLR 4.6.27414.05, CoreFX 4.6.27414.05), 64bit RyuJIT; ListBenchmarks.ListBaseBenchmarks.AccessByIndex()

Hi @yahorsi
From my experience (I am the person who was working on ensuring that the last few .NET Core releases have not regressed performance) such volatility is typically caused by memory and|or loop body alignment changes. I am currently working on a Workshop for the .NET Team and preparing a doc that provides some examples and describes how to deal with that: https://github.com/adamsitnik/performance/blob/e4987916c83bef9c2203c256043dc4d9f6cc6a29/docs/regressions.md#memory-alignment I hope that this doc answers your question. Since there is nothing actionable on the BDN side and we already have two issues that track the alignment ideas (#756 and #1513) I am closing this one. Thanks, |

Hi Guys!
I'm trying to investigate following benchmark https://github.com/yahorsi/ListBenchmarks where I'm trying to benchmark access to the List[]. The problem I see is that results are very volatile, sometime difference is 3x-4x and I do not understand why. And no, I do not run bitcoin miners on my machine and CPU/IO is not used when I run benchmarks :)
Below see how e.g. 0.0912 is different from 0.5830 ns.
Disasm looks strange for me as well. Why in once case it is so short and not in another case
