My API endpoint fetches some data from DB and returns to user (2.8KB gziped). I load tested this endpoint with 50 concurent connections per each second (loader.io, app hosted on heroku, build with node.js) and avg time was ~1300ms. Is it normal, slow, very slow?
I know that it depends on DB query time and complexity - I just want to know if this speed is good enough for production endpoint? It serves main content for single page app (in json format).
