atomiccounter_bench

This is the benchmark for different atomic counter libraries.

See atomiccounter for details.

Tested Libraries

• https://github.com/chen3feng/atomiccounter
• https://github.com/puzpuzpuz/xsync

Test Result

The flowing is one of a typical test result, the format is manual adjusted for easy comparasion.

Test environment is a MacBookPro with MacOS 12.5.1 and Apple M1 Pro chip.

To reduce the test errors, there are 10 calls in each op.
