Seeing a problem at work where the performance of the service we’re working on is just not good enough. Tried bumping up the EC2 instance size and raising the DB connection pool to 20. But the pool won’t go higher than 7 connections.
So it’s either that the connection pool is misconfigured, or the NATS Jetstream client has too few listeners. I suspect it’s the latter. I don’t know what the default is set to, but if it’s a multiple of the number of CPU cores, I’m not sure how well that’ll play with AWS EC2.
So that’s the next thing to look at.
