A system and method for processing a data packet. The method comprises initiating processing of a received plurality of data packets by CPU cores; tracking, by a scale management routine, processing queues for the CPU cores and their load. In response to an average size of a processing queue being lower than a first pre-determined queue threshold, and a CPU core load being lower than a first pre-determined load threshold, preventing adding new data packets to the processing queue, monitoring emptying of processing queues for each processing CPU core. In response to an average size of a processing queue or a CPU core load being above a second pre-determined upper queue threshold or the second pre-determined load threshold, transmitting all data from processing queues for each processing CPU core to a memory buffer, increasing the number of processing cores by one; and initiating data packet processing.
