Average size of network packets that an average user on the Internet generates is larger than 256 bytes. Network packets that are 256 bytes large or smaller are most commonly used in telecommunications or ISP infrastructure, banking systems or computer games. If a network interface of ten gigabits per second speed or faster is filled completely with such small packets, depending on the software and hardware configuration involved in the transmission and processing of the packets, there is a large probability that all packets will not be processed. For that purpose high speed data processing frameworks were created, out of which one of the most used is Intel Data Plane Development Kit (DPDK). In this thesis research was made on high speed traffic generator software, high speed data processing software and network performance of a physical computer, a virtual computer without DPDK support and a virtual computer with DPDK support was measured and compared by stress-testing them with the maximum number of packets of various sizes in order to determine how different use cases are behaving during the maximum number of packets is being sent. The results of research are commented, presented graphically and possible improvements are suggested in order to increase the number of processed packets in second.
