I would like to know if you're able to do a Stress and Loading test on a SPA website written in React with Apollo in the front, that's using as a backend Hasura Cloud Graphql (std version), where everything from the client goes directly through Hasura to the DB. DB is in Postgress housed in Heroku (Std 0 tier). Actually we're having problems doing those test, seeing how our SPA using mostly subscriptions. We are actually having trouble running those tests, as our SPA uses mainly subscriptions. So I would like to see the numbers you are getting, and how you have tackled it, seeing that we are having problem doing it with k6 and Jmeter. As a goal we are planning to have around 800 users simultaneously.
