  1. All tests are done with Xena Networks specialized test equipment (XenaBay),and done according to RFC2544 (Xena2544)
  2. Max throughput is determined with 30+ second attempts with 0,1% packet loss tolerance in 64, 512, 1518 byte packet sizes
  3. Values in Italic indicate that max throughput was reached without maxing out CPU, but because board interface configuration was maxed out
  4. Test results show device maximum performance, and are reached using mentioned hardware and software configuration, different configurations most likely will result in lower results
