This weekend I did mostly maintenance work on the server.
Since the amount of data in the DB outgrew the mariadb default settings, I did some fine-tuning of buffer sizes and binlogs. You probably won't notice it, but the DB update time is now pretty fast. It used to be 18ms, with the growing data it went up to 80ms and is now about 2ms on average. Pretty cool!
I've added a little feature as well: The stats page now shows the current players (what was displayed in the sidebar in the old wordpress days). You can check it out here.
