Re: more throughput if using more interfaces per machines ?
Hi Kevin,
Thank you for taking time to answer my queries :)
How do i make the OS ( FreeBSD ) to treat the 4 interfaces as a single
interface ? I have 4 different ip addresses assigned to each. ( client and
server )
Any commnad line paramater i can pass to iperf to do the same ?
Thanks,
Nirav.
