.NET 6.0 Update
Hi @JPWatson
I try to upgrade to netstandard and netcore3.1 to net6.0 then i run IpcThroughput
here's the result before upgrading

The environment i use is Amazon Linux 2022 on Graviton3 (ARM Neoverse V1) AWS c7g.
Looks weird. Will try to find out. It's also resulting the same stuff even after i try to disable/enable PGO and Tiered Compilation.
- Is that why you don't upgrade the dotnet and still use it for old .NET version?
- seems currently it's windows only? I might send pull request for Linux if that's interest you
Cheers
btw, after trying brute force for JIT runtime parameters finally arrived with this env var 🤣
export DOTNET_TieredPGO=1
export DOTNET_TieredCompilation=1
now i got better result i gues😄

Interesting results. Thanks, @welly87.
Is that why you don't upgrade the dotnet and still use it for old .NET version?
Targetting the lowest common denominator from a library perspective so I hadn't got around to testing the latest and greatest .net version.
seems currently it's windows only? I might send pull request for Linux if that's interest you
We've got builds running on both windows and linux. What are you seeing that's windows only?
basically first time i clone the repo and run IpcThrougput it show error

i try to restore the the nuget package but seems it can't resolve the HardwareInformation dependencies. It builds fine but have runtime errors. So i just commented this line
// ComputerSpecifications.Dump();
just to make the runtime happy....
another stuff that seems funny is when running on dotnet3.1 on Amazon Linux 2022/Graviton3 seems that nunit runner throw SSL errors when dotnet test (even if it's there)
The active test run was aborted. Reason: Test host process crashed : No usable version of libssl was found
Test Run Aborted with error System.Exception: One or more errors occurred.

but after i upgrade to .NET 6.0 it's magically disappeared. The good stuff is .NET getting better and better each release.
