What Hacker News says?
Historically, at its inception, .NET's GC was written in LISP and then transpiled to C++ with a custom converter. It is still a single-file implementation, but I'm afraid it's not 1000 but 53612 lines instead as we speak :) Well, that's not one file per se and there is more code and "supporting" VM infrastructure to make GC work in .NET as well as it does (it's a precise tracing generational moving GC), so the state…

HN discussionAh, I see where you are coming from. You are correct, sustained load heap size of SRV GC has been a known pain point that had been particularly exacerbated after beefy Windows Server hosts fell out of fashion and got replaced by 512Mi Linux containers. There has been work conducted on this each release throughout Core 2.1, 3.1, and then 5, 6, 7 and 8 versions to make it play nicer with more constrained memory limit…

HN discussionPer-core heaps. Count, sizes and proportions of generational heaps can also be scaled dynamically according to allocation rate, target % CPU time spent in GC and collection efficiency, like .NET's GC does. https://devblogs.microsoft.com/dotnet/put-a-dpad-on-that-gc/ https://maoni0.medium.com/dynamically-adapting-to-applicatio...

HN discussionIn .NET, GC is triggered when a user thread runs out of memory in an allocation budget and needs more, similar to what you described [0]. Generally speaking, indefinitely preventing GC from running is not possible (you always end up putting some data on the heap) therefore an optimal strategy is similar to any other language - limiting allocations and reusing memory through object and array pooling. This will ensure…
