Performance degradation about phpdotenv HOT 3 OPEN

We are running PHP 7.4, and yes opcache is enabled.

what the env files are you are loading are looking like

Could you please elaborate on this one?
Just one regular .env file, with a bunch of simple string entries, less than 10 variables that have references, no multi-level references, and no multi-line entries.

from phpdotenv.

Thanks for getting in touch. I am aware that v5 is slower than v2, and one reason for this is they have different features, and v2 has bugs that could only be sanely resolved by using a slower approach. I would be interested to know what PHP version you are using and what the env files are you are loading are looking like. I doubt the use of objects is what is the cause of the slow-down here, but I would certainly consider a PR that improves performance without introducing bugs, along with evidence.

In general, I would not recommend running this package on every request. Best practice is to use this package to parse your env file, one-time, then cache that across requests. v5 has a modular architecture, enabling this. For example, in Laravel, this package is used to compile a cached configuration file, one time, then that file is "required" by PHP at runtime, so we can make use of opcache, effectively meaning that here is zero IO on each request to load env and config.

I'd also be interested to know if you are using opcache. Loading 100 classes into fpm should make zero difference to performance, other than on the first request.
