  • they build to show explain that you have to add resource in sync to maintain performance. Need to leave them in.
  • MHUB refers to the chip on the FED. Not sure what it means but don’t need to spell it out.
  • What does the asterisk after “C” in the title refer to?It is the name referring to a number of drivers that are part of the PAI/O performance testing package
