This doesn't work?

I am not sure which apps are in the background. Anyway, results are pretty consistent.

Why the sudden interest on this benchmark?

I'm surprised that such an old machine is doing so well. However, only 2 apps in background, and CPU usage was idling at 8-10% prior to the test.

Mi 11 Ultra Snapdragon 888:

I was curious about the impact of QEMU on M1 Macbooks with x86 Docker images, so I ran this benchmark.

Specs:

• My device is 2021 14" MBP with M1 Pro and 32GB RAM.
• My Python version is 3.10.
• Docker has 11GB RAM and 3 cores available.

Below are the results:

• Running natively: 0.6509173749946058 0.6511464999057353 0.6511690000770614
• Running in a native arm64 container: 0.5683689580037026 0.5695775839994894 0.5701702090009348
• Running in an x86 emulated container: 14.544861840011436 14.5703257569985 14.61461971499375

So, as expected, the emulated container is much slower than the native ones, but I couldn't really figure out what was the deal with the Docker container being faster than running the script directly.

if someone is interested: running the benchmark on pyodide (python inbrowser, Node.js, based on WebAssembly), it runs about 1.3 sec per iteration. That is about twice as native. (MBA M1, firefox)

Looks interesting. I tested Rossetta compiled python (anaconda) and native python (miniforge)

Specs:

• Macbook pro M1 Max
• Anaconda python version is: 3.9.7, miniforge is 3.9.10

Anaconda:
1.3440638339999995 1.345124833 1.345285625

Miniforge:
0.637413166 0.6387493339999999 0.638863084

Maybe the list() on line 33 produces variations that depend on the memory manager or system load?

The benchmark could use just the range(), or precompute the list.

...I did the optimization, and it had no effect on my numbers.

    product = 1.0
