Hi @Alena Melnikova , there is a capacity and max capacity. The max is what determines elasticity but setting that alone is not enough. That is at queue level. You have to adjust the user-limit-factor so that a user can leverage more than just the capacity. You essentially are saying that a user can use X times capacity. For example, if you say 2 for user-limit-capacity in this example, the user will be able to leverage 80 percent (40x2) Capacity is the queue ceiling, you cannot set to 100 as the queues have to add up to 100 across root. I hope this helps. Ian
