AJAX Call intensity settings
With big communities, the amount of background calls required can grow quite a bit, especially if your users are using Chat a lot. Based on some reports and research based on them, we implemented more granular control over the intensity of these calls.
The Advanced Config tab was expanded with a new group called AJAX call intensity. There you can control how often an AJAX call is allowed to run when it’s active (for example people are typing in a chat window or there are new messages).
The old setting “AJAX Call Intensity” is now used to define how often a call can run when it’s idle (no new messages or any other activity). It also still controls the generic notification query (checking for new notifications, friend requests etc).
The third setting is a multiplier and it defines how quickly (or how slowly) the script should switch between active and idle intensity if there is no activity.
