[Winpcap-users] disabling chimney, was: Card info

[Gianluca Varenni]

The point here is not how to disable chimney. The point here is that if you have a 10Gbps NIC on your server, it's because you need a high performing network card during its normal operation (e.g. your server is a high bandwidth web server or similar). Disabling chimney because you want to run WinPcap on it can affect the performance of the whole server heavily. Just be aware of it.
Instead, if you are using a dedicated sniffing machine with a 10Gbps card, disabling chimney makes perfectly sense. Actually disabling TCP/IP completely on the network card makes even more sense.

Just my two cents

  Oh chimney..

   

  Run 'Netsh int ip set chimney DISABLED' from the cmd prompt.

  I have no idea if the card works with WinPcap or not (I think it implements TCP Chimney, WinPcap doesn't work if Chimney is in use), in any case don't expect to capture at Gig rates :-(

   

  Anyways, I would be curious to know how fast you can capture on these 10Gig cards.

   

  Have a nice day

    Hi,
        Someone tried this card with winpcap?

    Intel PRO/10GbE XF SR Server Adapter
    Tnx
