[Winpcap-users] Using WipCap to reduce CPU%

[Donald Woo]

I'm writing a VB .Net app to captured TCP/IP data from a source,  it is 
sending 406 byte packets approx. every 1 msec.  I can perform this capture 
but at a very high cost to the 
cpu,  somewhere between 98-100% !!!!    This is just from calling the 
stream read off the socket

                        'read data from socket
                        Dim nNumReadBytes As Integer = m_nsReadStream.Read(m_bReadBuffer, 0, g_nNumBytesToRead)

Can I use this to take the load off the cpu or do I need a packet capture 
card?
