The python overhead of to construct the queries exceeded the database overhead. We now prebake the queries that get frequently polled. This reduces the time it takes to update history_stats sensors and can make quite a difference if there are a lot of them. When using the mini-graph-card card, all the entities on the card being graphed are queried every few seconds for new states. Previously this would tie up the database if there are lot of these graphs in the UI.
