Scale hush house #72

Closed jwntrs closed 4 years ago

jwntrs commented 4 years ago

We scaled hush house from 2 -> 3 nodes, and in doing so we needed to also increase the max_connections to the db.

@cirocosta

heey, did we scale this one just to get the bump in the number of max connections, or something else? (e.g., cpu, ram, etc)?

The web nodes CPU were getting hammered.

It looks like we traded high web CPU for increased DB CPU, which is something we probably don't want. Ultimately we might want to go back to 2 web nodes but scale up the instance type. We're going to stick at 3 web nodes for the time being though to get a baseline on our metrics.

Either way this PR is to keep github in line with reality.
