  comment = {Using a hardware monitor they measure the I/O-bus usage on a
  4-processor Sun workstation. They characterize the bus contention caused by
  multiple different devices (disk, screen, and network). The contention
  sometimes caused significant performance degradation (to the end-user)
  despite the bus not being overloaded.}
