    s5000 psl High Dpc/slow network 2008 r2 x64

      Hi all!

       

      i have the following problem with an intel s5000 server board on windows server 2008 r2 x64:

       

      copy localy from c: c: 70 mb/s cpu usage between 20-70 % (minimum 1 core 100%)

       

      copy over gigabite network  to c: 15-25 MB/s cpu usage between 20-100% (minimum 1 core 100%)

       

      i installed all firmware upgrades, intel nic driver , ati es1000 driver and the chipset driver (but the chipset driver on 2008 r2 dosn´t show progress on clicking next the install completet screen appears! is this normal on 2003 it takes some minutes to install?)

       

      using xperf i figured out that ndis.sys going crazy during copy

       

      on 2003 i copy 100 mbit/s over lan to c: with 2-6% cpu usage!

       

       

      hardware: ssr212mc with 12x hdd 2tb RE4 WD(is there a firmware upgrade for the 12x expander??)

      8708 elp raid controller

      no other additional cards installed

       

      some one any ideas?

       

      thank you francesco
