    Microarchitectural performance analysis research is a pretty active and interesting area--see also: https://github.com/MattPD/cpplinks/blob/master/performance.tools.md#microarchitecture

  • xhyve

    xhyve, a lightweight OS X virtualization solution

  • There's also been a port of FreeBSD's bhyve to macOS for years: https://github.com/machyve/xhyve (which, in turn, is [or at one point was] used by Docker to virtualize Linux)

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • .NET Runtime

    .NET is a cross-platform runtime for cloud, mobile, desktop, and IoT apps.

  • To be fair, issues do exist. The .NET 5 SDK, for example, triggered a few Rosetta issues that were fixed in subsequent macOS releases, for example. (See https://github.com/dotnet/runtime/issues?q=+label%3Atracking-external-issue+label%3Aarch-arm64, e.g. https://github.com/dotnet/runtime/issues/44958#issuecomment-742645029)
