<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am trying to get the best performance out of winpcap library.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>We are capturing huge frames(each frame is 30 MB) over the Ethernet
interface using winpcap library.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I need to apply filtering to capture only relevant frames. I
use the following filter.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>“src 192.168.x.x”<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am using a 1Gig dedicated Ethernet interface for the
packet capture. 1 frame comprises of nearly 22,330 packets ( for the 30MB
frame).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am able to capture 1 frame in nearly 20s. If I remove the
filtering time improves to 5s. But I need to use the filtering to get only
specific packets.<o:p></o:p></p>
<p class=MsoNormal>Is there an alternate way to do this ? is there some way I
can improve the performance ?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I greatly appreciate your help<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks<o:p></o:p></p>
