Autoloader is very slow despite OPCache being configured #44604
Description
Impacted plugin
Jetpack
Quick summary
We're experiencing significant performance issues with the Jetpack Autoloader. The function:
Automattic\Jetpack\Autoloader\jp66cd040767dcc115cc8018307ec36356\al5_0_0\PHP_Autoloader::load_class
is one of the slowest parts of our WooCommerce site, with load times around 0.48 seconds and 1,353 calls on a single page load.
This issue is all over the site and i don't understand why this is so. Even on my local development setup where i use macbook pro m3 the time is significant. I am using code profiler plugin to profile the page.
