Receive Rate Behavior in WinPcap</DIV>
<DIV><BR></DIV>Hello
Everyone,<BR>
I'm having a small issue with a small application I wrote which uses jpcap; a
java wrapper for Winpcap. I have written a client-server app in java. I'm
using jpcap to listen and send packets from client to the server. My problem
is that when I send a large burst of packets, 99% or so of the packets
arrive at the rate they where sent, then there is a stall for a few seconds
before the final ~1% packets are received. When I used Wreshark to
monitor, I saw the same behavior. Has someone come across this problem before?
Is this a known issue winpcap? <BR> <BR>Thanks for your
help,<BR>Omar<BR><BR>
