Hi folks
I need to check transfer rate between my device . There are some tools to check it out?
I'd like know if I negotiate a really gigabit ethernet connection or not...

Thank you

Yep, iperf is what you want. You'll need two machines, one as the client and one for the server.

It's fairly simple. You use two machines: one for a server and one for a client. It really doesn't matter which system is in what role; they are simply connection points.

To test TCP (normal bandwidth testing), you execute the binaries as follows on the server:
Code:
iperf3 -s

On the client, you run the following:
Code:
iperf3 -c <IP Address of server>

For proper testing of a local system, you want to be on the same subnet, otherwise you may find a router that cannot route that fast. Of course, you may find the local switch to be a bottleneck too, but that's rare these days.
