If you mean iOS, it is more a side effect of the project failure to add GC to Objective-C than anything else. Also reference counting only applies to a tiny subset of Objective-C data structures, classes derived from NSObject using Cocoa retain/release patterns. If you add Swift to the soup, there is still quite some work to do regarding performance, https://github.com/ixy-languages/ixy.swift/blob/master/perfo... The other, even bigger OS, is running on tracing GCs. And Windows is running on a mix of reference counting and tracing GC.
In Show HN: A pure reference counting GC in Go
emmericp·Sep 12, 2019
Swift spends 76% of the time incrementing/decrementing reference counts; ARC is just very bad at pushing tens of millions of objects through it every second. There's some more evlauation for Swift here: https://github.com/ixy-languages/ixy.swift/tree/master/perfo... It's just a coincidence that JavaScript and Swift end up with almost the same performance; there is nothing similar between these two runtimes and implementations.

Didn't say they weren't. Not sure if you misunderstood my comment. It's a mistake to extrapolate too much about the "reference counting vs tracing GC" question from this one low-level driver benchmark. In fact reading their paper, they don't understand why Swift ARC traffic was so high.[1] They weren't allocating a lot of objects or copying. It's probably just an unoptimized use case or bug, not something fundamental in the memory management model. Swift is still quite young.

Personally, I'd call this writing "Safer and More Secure Drivers in High-Level Languages", because there are still unsafe operations going on (for DMA, etc.): https://github.com/ixy-languages/ixy.swift/search?q=Unsafe While it's great that you get improved safety (and often nicer and easier to reason about code) by using something other than C, you can still have memory safety issues from cavalier or incorrect usage of unsafe APIs, since they undermine the guarantees the language provides with regards to correctness. Also, unrelated: does anyone actually have the slides (you know, the presentation file with text in it, rather than the mp4 that CCC is offering me) for this presentation? It's really annoying to scrub through a video to find stuff on a slow internet connection :(
