Hi,
The docker image is built from source. Maybe you checked the wrong one?
Here is the Dockerfile[1]
[1] https://github.com/docker-library/php/blob/master/7.4/buster/fpm/Dockerfile
** Summary changed:
- PHP from the official Docker image performs much better than the Ubuntu
packaged version
I retitled the bug as even the version of PHP from the Docker image is
pulled in binary form. It is not compiled from source on the user's
machine.
** Summary changed:
- PHP Performs Much Better Than This Package When Built From Source
+ PHP from the official Docker image performs much better
