As OpenSIPS core is not async, the whole chain of processing a message can cause this. Practically, summing up all RTT for all your database queries, DNS lookups, Radius requests, media reservations can cause this.
The farther away each component is the poorest the performance as that child cannot process any new packet until is done with the previous.
