Performance degradation in CA1416 on large solution

Analyzer

Diagnostic ID: CA1416

I see performance problem with CA1416 on my solution.

Configuration

Solution with ~260 projects and >1m lines of code (not open source, cannot be shared)
Problem originally confirmed with dotnet 6 but also confirmed with net 8.
Enabled CA1416, solution contains >12k warnings from CA1416
Use MSBuild from Visual Studio 17.9 Preview 2: C:\Program Files\Microsoft Visual Studio\2022\Preview\MSBuild\Current\Bin\MSBuild.exe

I don't know how to trace MSBuild. MSBuild run from dottrace generate trace without any usefull info. So I attached to Visual Studio ServiceHub.RoslynCodeAnalysisService.exe and Run Code Analysis on Solution:

Most of time spend on adding element to ConcurrentDictionary:

private static bool TryGetOrCreatePlatformAttributes(ISymbol symbol, bool checkParents,
    bool crossPlatform, ConcurrentDictionary<ISymbol, PlatformAttributes> platformSpecificMembers,
    SmallDictionary<string, (string relatedPlatform, bool isSubset)> relatedPlatforms, out PlatformAttributes attributes)
{
    if (!platformSpecificMembers.TryGetValue(symbol, out attributes))
    {
        // < some code >

        attributes ??= new PlatformAttributes() { IsAssemblyAttribute = symbol is IAssemblySymbol };
        MergePlatformAttributes(symbol.GetAttributes(), ref attributes, crossPlatform, relatedPlatforms);

        // This one:
        attributes = platformSpecificMembers.GetOrAdd(symbol, attributes);
    }
