I just wanted to provide an update here that our Dev team was able to look into this and replicate the issue. They weren’t able to uncover any obvious culprits in this, but the best guess so far is that MySQL may have optimizations for Windows that don’t exist in MariaDB. For now our best recommendation is to continue using MySQL if the performance is a blocker. I’ve changed your post to a Bug for others to vote, comment or follow at this time. We don’t have any kind of ETA on a solution since the scope of this is quite limited, but we will monitor and update along the way.
