as well with the Wire shark. After hitting 20000 packet/sec it becomes kind of stagnant.
There is a site recently we were able to handle 80000 packets/sec on gigabit

style='font-size:10.0pt;font-family:Arial'>Thanks for the replies. Here is the
summary for what I have done after your responses:</span></font></p>
</div>
<div>
<p class=MsoNormal style='margin-left:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>- I have built a win32 application
with visual C++ and listened for the incoming packet. The code segment for
listening is just a for while loop with pcap_next_ex() function and when a
packet arrives a counter is incremented. Thats all, no displaying or saving to
disk. As a result only 20K of the packets are captured. </span></font></p>
</div>
<div>
<p class=MsoNormal style='margin-left:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>Again I am able to see that about
400.000 packets are received on the LAN status window in the system tray which
means the NIC has captured them succesfully, but I can capture very small
amount of it.</span></font></p>

style='font-size:10.0pt;font-family:Arial'>I am really suprised that only small
amount of the packets are captured by the driver?</span></font></p>
</div>
<div>
<p class=MsoNormal style='margin-left:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>Do you have any other suggestions?
or has some ever tried to capture large amount of packets/second (e.g : 60K
packets/sec) using winpcap?</span></font></p>
