Slow maria-db behaviour when 1000 users are chatting together

Hi everybody,

I have 1000 users connected that are chatting together (simulated with Tsung) and I want to use two of my clients to chat as well (these are real clients and not simulated with tsung).

The problem is that the two clients cannot send and receive messages when there are the other 1000 users chatting together. This strange behaviour disappears if I use the embedded DB instead of MariaDB.

Is there any particular DB configuration to support this number of user?

I use MariaDB 10.x and Openfire 4.0.1

Thanks to all.

Nobody can suggest me something?
