Openfire on docker really bad performance

hi There,

I am new to openfire and chat services in general. I am working on a chat service that will be integrated in a custom mobile app.

We have created a docker container from here and updated to version 4.0.1 of OF.

We use pidgin and/or empathy chat clients, but performance is really bad.

Before a new chat popsup it takes 30 seconds up to 120 seconds… way to long even with only 5 users in a room.

How can I go about starting to check what is wrong?

The container has enough memory available . No clue were to start, any directions appriciated
