Speed is greater than port speed

[Igor-Shabalin]

I have a 1G port speed, but:

Why ?

Also curious if my results are accurate. I have AT&T fiber. It's supposed to be 1 gigabit, but speedtest++ shows ~1.5 gigabit. Great if true!

Scratching my head a bit though, cause I didn't think my little Edgerouter-X could push incoming packets to the LAN this fast... but maybe?

@Igor-Shabalin Many ISPs will over-provision a little or allow for "burst" traffic. You'd have to measure over time to see if this pattern holds. There can be small measurement errors, but they should not amount to >30% I believe.

@mmarshall540 EdgeRouters and USGs etc. should use hardware offloading when IPS is disabled (which it is by default) and can then easily push gigabit speeds. Re the speed, same holds: Try watching the measurements over time, you might have gotten burst traffic or AT&T's traffic shaping might be slow.
