What is an acceptable amount of Dyno load?

Issue

Dashboard Metrics displays Dyno Load, measured as "1m Load Average" and "1m Load Max". The method of taking these measurements is explained on our Dev Center (https://devcenter.heroku.com/articles/metrics#dyno-load), but this does not illustrate what you should expect my application to run at.

Resolution

Free, Hobby and Standard Dynos

Free, Hobby and Standard Dynos run on shared systems, and as such, you should aim to keep maximum Dyno load to within 0.5 and 1.0 to avoid any potential degradation of performance.

Performance Dynos

Performance Dynos are single tenant, this means that your Dyno will have full access to the resources on the system. For Performance-M Dynos, your should aim to keep your maximum Dyno load to within 3.0 and 4.0. For Performance-L Dynos, your should aim to keep your maximum Dyno load to within 12.0 and 16.0
