php 7.4 vs php 8 vs php 8.1

Dear all ISPConfig experts,
I am very happy with ISPConfig 3.2 default php 7.4 set up.

As there are also php 8 and php 8.1 available for web service, so how do you compare different php version performance on heavy php applications like Laravel, Wordpress, etc.?

1. php 7.4
2. php 8.0
3. php 8.1

Please share your experiences.

 

Use same website that supports all the three php and test them using one php to another..

 

php 8.0 works but I cannot feel the difference between it and php 7.4.

 

Feel?
