Probably FIFO buffers are filled up... Nios is VERY slow doing ethernet data transmissions, especially when You use InterNiche and RTOS. Don't expect anything more than 10-15Mbps.

Thank you for your reply, Socrates.

For me,10-15Mbps is enough, but the speed is much slower than 1Mbps.(I'm using 1000Mbps & full Duplex mode).

I ported Benchmark example in AN440 to this hardware design, and found the transmit speed is just 19k/s using TCP. And the transmission can not always get done(sometimes there is send() error).
