[Winpcap-users] Better Performance

Before trying to modify the WinPcap source code, I would try to understand what the bottlenecks are. What are you doing with the received packets?

Can you show us the packet processing loop that you have in your code (even in form of pseudocode)?

Have a nice day

  Subject: [Winpcap-users] Better Performance



  I am trying to figure out how to capture image frames most efficiently.  Each frame is approximately 20Mbytes.


  I am trying to achieve frame rate of 1-2 frames per second.  The packets are being received over a Gig eth dedicated link. ( Packets are sent over that link using only one source).


  I am unable to achieve this frame rate using winpcap. Would it be helpful to modify the Winpcap source code for better performance ? Has anyone here have any experience in modifying the winpcap source to achieve higher frame rate capture ?



  Thanks for your help in advance
