  • The Performance Impact of C++'s `final` Keyword

    Yes, that is true. I'm not sure about JVM implementation details but the reason the comment says "virtual and interface" calls is to outline the difference. Virtual calls in .NET are sufficiently close[0] to virtual calls in C++. Interface calls, however, are coded differently[1].

    Also you are correct - virtual calls are not terribly expensive, but they encroach on ever limited* CPU resources like indirect jump and load predictors and, as noted in parent comments, block inlining, which is highly undesirable for small and frequently called methods, particularly when they are in a loop.

    * through great effort of our industry to take back whatever performance wins each generation brings with even more abstractions that fail to improve our productivity

    If you care about portable SIMD and performance, you may want to save yourself trouble and skip to C# instead, it also has an extensive guide to using it:

    CoreLib and many new libraries are using it heavily to match performance of manually intensified C++ code.

    We might not be that far away already. There is this issue[1] on Github, where Microsoft and the community discuss some significant changes.

    There is still a lot of questions unanswered, but initial tests look promising.

A lot of them can be built and used individually, which is what contributors usually do. For example, you can clone and build and use the produced artifacts to execute .NET assemblies or build .NET binaries.

    Yeah, it kind of is. There are quite a few of experiments that are conducted to see if they show promise in the prototype form and then are taken further for proper integration if they do.

    Unfortunately, object stack allocation was not one of them even though DOTNET_JitObjectStackAllocation configuration knob exists today, enabling it makes zero impact as it almost never kicks in. By the end of the experiment[0], it was concluded that before investing effort in this kind of feature becomes profitable given how a lot of C# code is written, there are many other lower hanging fruits.

    To contrast this, in continuation to green threads experiment, a runtime handled tasks experiment[1] which moves async state machine handling from IL emitted by Roslyn to special-cased methods and then handling purely in runtime code has been a massive success and is now being worked on to be integrated in one of the future version of .NET (hopefully 10?)

    The math of the above is really simple. Microsoft has 13,000 stars on their GitHub profile for their flagship product. SupaBase has 63,000 stars on their GitHub project for their flagship product. 27% of all software developers in the world are using .Net. SupaBase has 4.5 times as many likes as the .Net Core runtime, so they must be 4.5 times as large, right? 4.5 multiplied by 27% becomes 130%. Implying 130% of all software developers that exists on earth are using SupaBase (apparently!)

What are some alternatives?
