My current project makes use of the MySQL database, which runs in a Docker container.
At a certain moment connecting to the database became excruciatingly slow, taking tens of seconds to establish a single connection. After that everything would work as expected.
The application opens a connection some hundred times, so the startup time had become really unacceptable.
I’ve spent a lot of time hunting that down, and then even more time looking for a solution as I failed to find any on StackOverflow. But finally I’ve solved this.
