It's a bit painful to setup, but in general with 9k jumbos 

and TSO we

were able to get close to pci-x 133 limit - both in LAN and 

WAN tests.

Cool, but a very specific environment, no? ;)

Define specific environment :-). We are running common tcp benchmarks like
nttcp or iperf or Chariot or filesystem applications on a very generic white
boxes, with generic OS/settings.

What concerns me about all this is that it seems so very 
host-centric design. Wouldn't it be nice if we had a little 
bit more network-centric worldview when designing network 
infrastructure?

It isn't just a matter of how had we can push stuff out, it 
also matters how much the network can take.
Blasting tens of gigs into the ether seems all very exciting 
sexy and cool, but suited for dedicated links or network 
attached storage channels, not general-purpose networking on 
the Internet or intra-nets.

This is somewhat different from IB or FC "miniature networks", 
some/most of 10GbE testing runs in existing datacenters or over 
existing long-haul links - see for example

Cheers, Leonid

And if that is the case, we're talking about a much smaller 
market (but perhaps a more profitable one ;))...
