In some cases, ie. joined many active MUC rooms, current limit on no. of items in stream management queue for a single connection (2000) is too small and causes disconnections.

It would be desirable to create a burst period and burst period limit ration, allowing temporary (in the burst period) limit to be multiplied by burst ratio.

Assuming limit of 2000 packets with burst of 10 seconds and ratio of 20 it would allow for a period of 10 seconds to have up to 40000 unacked packets. As ratio and period would be configurable, it would allow us to have more flexible limits.
