      3 USER LEVEL PERFORMANCE
      4 ----------------------
      5 
      6 If your system is correctly configured with GbE and a GHz processor, 
      7 you should expect user level iSCSI performance similar to the following.  
      8 This output was generated by running utest against a target running uramdisk.

     32 KERNEL LEVEL PERFORMANCE
     33 ------------------------
     34 
     35 Kernel level performance (ktest to kramdisk.o) should be similar to the output
     36 shown below.  Note that this test does not go through the linux storage stack,
     37 but is rather a kernel level iSCSI test with no attached filesystem or SCSI
     38 midlayer.
     39 
     40 This output was generated by installing the module intel_iscsi.o and then 
     41 running "ktest <device>" where <device> is one of your iscsi devices (e.g, 
     42 /dev/sdb).  Although you specify a single device on the command line, all 
     43 target devices are tested.
