Re: Getting good performance from e1000

Hi,

before sending out new question, let me answer my old question (for the 
archives):

After some discussions with (co-) authors of netperf and e1000, we 
reached the conclusion that this test is not valid. Either one should 
use the TCP_STREAM on one end and TCP_MAERTS on the other or TCP_RR with 
multiple "bursts", i.e. compile netprf with --enable-burst and run with 
the test with -- -b 4 for example.

With this we were able to get very good performance measures throughout 
all mtu settings, albeit we needed MTU of 3000+ to get "line" speed.

Sorry for the late answer.
