    Windows Server 2008 poor performance


      Hello, i'm doing some test with infiniband, actually i have 2 server Dell poweredge R710 configured as follow:


      48GB ram

      2 x intel xeon x5660

      single HCA MHQH19B-XTR

      Windows 2008 R2


      to connected eachother i used the following cable CINCH - QSFP+ http://www.cinch.com/wp-content/uploads/cinch-qsfp-cable-rep-training-2010jan18-part-1.pdf

      I updated the HCA MHQH19B-XTR firmware to latest and installed the windows driver on both windows server (MLNX_VPI_WinOF-4_90_All_win2008R2_x64.exe)

      executed opensm.exe and the server can ping eachother.....

      If im trying to transfer a file from servers i can get a transfer rate between 90 and 150 Mb/s, i tried everything but i cannot understand what's wrong.....

      somebody can help me ?
