delay..</DIV></DIV></DIV>
<DIV><BR></DIV>Hello!
<DIV><BR></DIV>
<DIV>Gianluca, can u run this code on Your machine and running the Wireshark
save the log and send it to me, please..</DIV>
<DIV>Is there any delays, i mean delays between the packets that Wireshark
(winpcap) capture?</DIV>
<DIV><BR></DIV>
<DIV>P.S. code from WinPcap documentation, sending packets, not one, but 10000
(or 1000000)..</DIV>
