All throughput tests done with Xena Networks specialized test system and RouterOS v5, according RFC2544, with Ethernet frame sizes 64, 512, 1518 bytes.
Each board is tested with specified number of Ethernet interfaces, to ensure optimal load on hardware.
Values in Italics indicate that the maximum possible throughput was reached, limited only by ethernet ports themselves.
Test results show device maximum performance, and are reached using optimal hardware and software configuration, different configurations most likely will result in lower results.
