Slow execution time when running inside Docker container on a M1 CPU (aarch64)

[david224-ic]

What happened?

I noticed that after implementing envkey-php in my project page loading got at lot slower only when running inside my Docker container (I'm on and M1 Mac).
I decided to take a look at what was causing the slow down with a profiler and I found out that a shell exec called by envkeys-php's fetch() function was responsible, located at:

envkey-php/src/Fetcher.php

Line 69 in fe151c6

$res = rtrim(shell_exec($cmd));

)

The visualization of the profiler's results:

My analysis

I decided to try and debug it, and found out that this class ends up matching envkey-source binary for linux/amd64 when used inside the container, which runs a lot slower than the linux/arm64 binary on my machine of course.
I believe the cause of this behavior lies on the code (in the snipped bellow) that calls php_uname('m') to determine the cpu arch, but it can only match 'arm', while running uname -m inside the container yields 'aarch64'.

} elseif (stristr(PHP_OS, 'DARWIN') && stripos(php_uname('m'), 'arm') !== false) {
