quantum-server by default will create an sqlalchemy_pool of 5 connections. This will start to fail as more and more data is added. Raising it to 40 seems to stop the problem, it may need to go higher. Raising it to 20 still results in:

TimeoutError: QueuePool limit of size 20 overflow 10 reached, connection timed out, timeout 30

Raising it to 40 seems to have restored responsiveness. I suspect it may be too low as the number of clients increases.

[DATABASE]
sqlalchemy_pool_size = 40
