We can revisit the hard code later, if needed. I don't think it will be.

I love this. I hope people understand that an average of 22ms and a median of 17ms means that on the whole, PostgreSQL is way faster, in spite of the p95, p99, and "slowest" being slower than SQLite.

Changed a hashing algorithm that allowed us to scale >100x higher from an agent check in perspective, allowing for thousands of agents instead of hundreds. Added documentation and results from scale tests, and made adjustments to the connection manager UI to add search / filtering so that the new scale is more usable.
