Subject: Re: [Wireshark-users] Ideas for 10G capture platform?

I'm also curious.  Although I'm assuming we're in a similar state to the capture situation with 1Gig Ethernet 8 or so 
years, where:

- Few NICs could actually receive and process packets at line speed.
- A surprisingly large number of NICs refused to enter passive mode, and some had problems allocating buffers properly 
for jumbo frame handling.
- There were few, if any, inline capture solutions that could capture bidirectionally, though fiber taps were possible. 
 Copper taps were not yet available.
- For extended captures (more than a few seconds), disk speed is a tremendous bottleneck and nowhere near 
linespeed+full packet capture is possible, even with modestly-expensive RAID solutions.
- Host BUS speeds actually became a problem, either becoming a quick bottleneck when others (NIC+disk) were loosened, 
or exacerbating them.

...But I have done no testing of my own this time around.
