Compared to jumbo frame MTU=9000 bytes, Acenic Gigabit Ethernet Card can almost reach the media speed for TCP_STREAM throughput test; same test result for nomal MTU=1500 bytes is about 650Mbits/s. The PACKET_STREAM test result for MTU=1500bytes is pretty good too, it is around 900Mbits/s. Theorically TCP_STREAM throughput test for MTU=1500 bytes should be above 900Mbits/s. Does anyone has any idea why not?
