I view that story as a good example showing why it's important for independent developers to have individual access to well-performing hardware.In case you missed it, there's a performance issue on Arm 64-bit Linux fixed in 6.18. Here's the link:

I wonder what latencies per-CPU atomics have in Linux on IBM Power 11. If no hardware is available suitable for individual developers, there are many things that will never be fixed or optimised.
