<p class=MsoNormal>I’ve searched the FAQ, docs, and mailing list, but
couldn’t quite find an answer.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m writing a speed-sensitive application that needs
to process large volumes of packets live. I’d like to know if the app is
keeping up with traffic, which means I need to know if wpcap’s kernel (or
user?) buffer is ever overflowing and dropping packets (caused, of course, by
my app not emptying the buffer fast enough). Is there a way to tell if I’m
reading wpcap’s buffer too slowly?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>On a related note, if I dump packets to a file and then
capture from the file, is there any timing information associated with that?
Ie, can I read from the file at the same speed/timing distribution that the
packets were captured at? If so, I’ll simply save some traffic to a file
and then when my app is done, compare the amount of packets in the file to the
amount my app read to see if any were dropped.<o:p></o:p></p>

<p class=MsoNormal>Thanks!<o:p></o:p></p>
