I just did a performance test with a GEIP+ and could get 400 Mbps through
it with 1000 byte packets. Just a data point since I tested it yesterday.
For the umteenth hundredth time. That card was never designed to do
GIG to GIG traffic. It was simply a physical layer gig *migration*
for aggregation router uplinks as customer migrated their cores to gig links
followed by upgrades in the aggregation routers for full gig speeds.
We had tons of customers askign us for this knowing well that they
would never exceed the capability of the card given their aggregation
density.

It was a transition card and while it can't do extremely high rates
I've seen it work perfectly in hundreds of routers in the aggregation
space.

Just another data point.
