Do you have more exact information? I mean:

 - Description of the test setup.
 - How packet stream was generated?
 - How success/loss was measured?
 - What hardware was used: CPU, mobo, NICs.
 - What settings were non-default.
 - And finally exact numbers - pps success/loss.

And don't waste your time comparing 5.x and 4.x. Please
compare 4.x and 6.0. The 5.x is a previous step.
