We don't send all your method calls to APM. If so, we can't handle that amount of load. Instead we pick outliers and send them to the APM. So it doesn't matter how many subscription calls you've for a second.
In the future, we'll let you decide the outlier value, rate and some other params to customize it

For example, the app I'm instrumenting is in private beta so subscriptions or method calls happen very rarely. Seems that I can see individual method or Meteor.subscribe calls as spikes in the Response Time graph, then I click on them, and see a button for the trace.
But what happens with a frequently used app, when many subscription calls will be made per second? Will an average be displayed in the Response Time chart? What if I click on it, what traces will be displayed? Will APM choose the slowest ones perhaps, up to a limit?
