[Winpcap-users] winpcap-app looses packets on full duplex GigabitEthernet connection

[Gianluca Varenni]

Wireshark definitely is not the right tool for a full gigabit link: it 
always dumps the packets to disk, and a standard disk cannot keep up at that 
speed.

What are you doing with the packets in your application?

Have a nice day
