[Winpcap-users] questions about latency with winpcap

We are writing an application that requires consistent small latencies in
obtaining packets from the network.  We are grabbing UDP streamed packets
from the network and then playing the multi-media stream.  Currently our
overall program has unacceptable latencies so we are dissecting it to
understand exactly where the latencies are.  I’m concerned it may be in the
networking piece.  Can you help me understand what type of latencies we
could expect in grabbing packets.  I would like to see sub-2ms.  Are there
certain tricks to obtain this type of latency?

We are programming in a Windows environment using Pcap to simple retrieve
the packets for our application.
