​​ Additional details

​​ New users per minute

When you configure new users per minute, this value is not the number of users added per minute.

Instead, it is the threshold of users allowed per minute (less than or equal to the number of total active users). You should set this value at 100% of your expected peak traffic to ensure users are only queued when necessary.

​​ Session duration

Session duration improves user experience in two ways.

First, it prevents visitors from having to pass through a waiting room twice for the same transaction. For example, a visitor might want to make a purchase at There’s a lot of traffic at, so they queue in the waiting room before entering the online store. After a period of time, they leave the waiting room and enter the online store. They make a purchase and leave the online store.

However, they forgot to add a note to the order or request a receipt. As long as their session cookie is still valid (for the length of time specified by the session duration), they can re-enter your application without having to re-queue in the waiting room.

Second, session duration lets your waiting room create a dynamic outflow from your application (in addition to dynamic inflow). A user’s session cookie expires after a period of inactivity, meaning that new spots can open up as soon as space becomes available and estimated wait times are lower and more accurate.
