Question: PHP 7.4 with Preloading in CI 2/3 possible?

I don't think that you will get large benefit with CI 2/3 ..
The framework is with light footprint so even if it is preloaded this won't gain much performance boost..

Thank you for your reply. However, I'm not interested in an opinion about whether it's a good use of time and energy. I'm asking if someone with experience can comment if it's possible, as well as any further comments about implementation.
