    Lancard promiscuous mode (etw loggin) problem




      With Intel Lancard (Intel® pro/1000 PT Dual port server adapter),

      We used it for Packet Mirroring System.


      When Promiscuous mode was set and IP address was not set to that card.

      It seems that intel adapter driver write the log every 5 or 6 minutes. (ETW Logging).

      This logging uses tremendous CPU resource so the hole system was taking effect by it.

      (We generally received about 500~1GB data /sec)


      We tried everything for this problem, and finally we knew that when the adapter set IP address,

      it is not write any log about it and the system performance was great.


      At this time, we would like to know if there's any KB or any other workaround about this.

      Because we must suggest to our customers that set IP address for this LAN card for the system performance.


      Any advice is welcome.

      Thank you for reading this.
