Surprisingly on Apple M2 (ARM) atomic is inferior to mutex.

g++ -std=c++20 -O3 atomic_vs_mutex_cnt.cpp -pthread
python3 run_counter.py > counter_perf.csv
pip3 install pandas seaborn
python3 plot.py

see result in mutex_vs_atomic_m2_chart.png

Testing Functions for Go

Below is a small collection of testing functions for Go. You don't need to import this as a dependency. Just copy these to your project as needed.

No, seriously. They're tiny functions. Just copy them.
