Re: Virtual NICs: Only 1 Gbit or better more?

Hi,

I measured it with iperf now, in exactly the same way like the guy in the link you posted.

I get just a little bit more speed than 1Gbit, but not really significantly.

Both clients are on the same vSwitch and same ip subnet (so they never pass an external link, which might have limited it to 1 Gbit):

C:\Users\admin\Desktop\iperf-2.0.5-2-win32>iperf.exe -w 1500k -l 512M -t 30 -c 10.21.1.4

------------------------------------------------------------

   Subnetzmaske  . . . . . . . . . . : 255.255.128.0

   Standardgateway . . . . . . . . . : 10.21.127.254

...

But you are right.  Its more than a GBit.  Possibly with the same vNIC under Linux its even more, i didnt test that yet.

So, to come back to my original question:

Do you think its basically a good or bad idea to aggregate several vNICs to lets say 2 or 3 GBit Interfaces?

Thx in advance
