Hi,

I'm a spinner, I'm a sinner
I spin on CAS loops for my dinner
Some call it busy-wait, I call it fate
When the queue is empty, I just rotate

2 Producer threads, 2 Consumer threads
Each Producer generating 8192 items
the single common channel between
them 128 elements large.

public class DmitryVyukov
8 ms
public class DougLea
10 ms

On the Ryzen AI 7 350 which has 8 physical
cores with hyperthreading, making it 16
logical cores.

LoL

Bye
