How get capacity of network in Amazon AWS EC2 instances?

Question

I want to get Maximum Capacity for network interfaces in Amazon EC2 Instance?
when I used this command:
$ sudo lshw -class network
the result is:

$ sudo lshw -class network
  *-network
       description: Ethernet interface
       physical id: 1
       logical name: eth0
       serial: 0e:bf:3b:c5:cd:20
       capabilities: ethernet physical
       configuration: broadcast=yes driver=vif ip=10.0.1.14 link=yes multicast=yes

but I need capacity that here you can see as a result.
could someone help in this case?

Answer 1

It's a virtualized network card in EC2, so there isn't a capability value available.

There's a table here that shows the network bandwidth available to many of the instance types. For types not documented, you can start up two identical machines in the same placement group, and use iperf to measure it, rounding up to the nearest sensible value.
