Okay, I have done some of my own testing with 10,000 packets I am not seeing
any delay at all.

Without 100,000 packets however, I am seeing some periodic delays.


My test is not good. It is not the same test as yours.

I do not have an oscilloscope so I cannot know if the packets are being SENT
without delay. I suspect they are.

I suspect the delay I am seeing with my test is from the SENDING machine,
not on the receiving/capturing machine.

So my test in inconclusive. It proves nothing.

Alimjan, are you absolutely certain there is no delay sending? Does your
oscilloscope have a "record" feature? Can you review your oscilloscope
recording to verify there are zero delays? It is important!

In other words, do you have ABSOLUTE *PROOF* that the packets are being SENT
without delay?
