P99 is usually <100ms which is excellent, but occasionally has big
spikes to 1000ms. This is only on the record index.
I don't want this to get out of hand. I've ran a few test queries and
they all complete very fast, and are purely index scans.
Hopefully this helps figure out if it's a specific user with tonnes of
stores or something? Otherwise there could be something up with my db.
I should probably also figure out some proper log levels or tracing lol.
