Mysql docker performance

[paales]

As measured when running a query inside the docker container to mysql we see a network latency of 0.281ms compared to 0.085ms on dedicated server.

Assigning to @wimvdputten. He's been testing out some changes that don't use a bind mound for the MySQL service but simply allocate it on the shared virtual disk, which greatly increases performance.

Downside is that MySQL files can not easily be included in local backups, but most of us exclude these from backups already anyway.
