+### What's the difference between "Experimenter" and "Nimbus"?
 
 Nimbus is the code name of the experimentation project, so Nimbus refers to **the whole experimentation system** (handles enrolling/unenrolling users, sending branch configurations, etc). Experimenter is the **customer interface to both Nimbus and Jetstream** that you access at http://experimenter.services.mozilla.com/. In Experimenter, users can configure experiments, manage them (launch, monitor, end), and can see the results.

+- Nimbus uses remote setting to get changes to users.  Remote settings pushes updates to its CDN once an hour.  Then it has geoip specific dns resolution and caching and etc.  
+
+- Depending when you make your change and when RS propagates to CDNs - it could take minutes to just over an hour.
+
+- Desktop clients only recompute enrollments at startup and every six hours thereafter.
