You can't ever get more traffic on an aggregate than what one link
will do to a single host. Specifically, one conversation always flows
over one link, what bonding does is either standby's a link for HA, or
distributes conversations across many to see global throughput as a higher

So, no, you won't see "speed" improvements with a tool like iperf in the
sense I suspect you are trying to see it.

What you could do is have 8 1gig hosts send/receive nearly 1gig of data
simultaneously to a single server with a 8 interface aggregate if setup
appropriately. (Other factors apply, but this is generally how it is)
