take the speedtest , only 200M , just 1/5 of the bandwidth 。

is there any restrictions between WS-C2960X-48TS-L  and  WS-C2960X-48FPS-L ?

Take the switch out of the equation and directly connect this same machine to the router, what is the result of the speedtest?

[ooopps201406]

1000M direct on router , without switch .   should i set  port-channel   with 5 ports uplink to router?

What kind of machine was used to test this?

Can we see the screenshot of the result which shows up as 1 Gbps?

Wut?

What is the model of this router?

What is the CPU of the PC? 

What is the model of the HDD in this PC? 

There is no way a simple PC can process 1 Gbps of traffic much alone "speed test".  

Try this test:  Disable all the downstream ports of the stack of 2960X except one.  Plug this PC back in and re-do the "speed test" .  What is the result?

[ooopps201406]

OK， deny the other downstream  and retry the test later

What is the make and model of the router?
