  28 This tool tries to gather some CPU/Hardisk performance data on the
  29 hardisk (mounted at 'path').
  30
  31 * CPU BOGOMIPS: bogomips sum of all CPUs
  32
  33 * REGEX/SECOND: regular expressions per second (perl performance
  34   test), should be above 300000
  35
  36 * HD SIZE: harddisk size
  37
  38 * BUFFERED READS: simple HD read test. Modern HDs should reach at
  39 least 40 MB/sec
  40
  41 * AVERAGE SEEK TIME: tests average seek time. Fast SCSI HDs reach
  42 values < 8 milliseconds. Common IDE/SATA disks get values from 15 to
  43 20 ms. SSD seek times should be below 1ms.
  44
  45 * FSYNCS/SECOND: value should be greater than 200 (you should enable
  46 'write back' cache mode on you RAID controller - needs a battery
  47 backed cache (BBWC)).
  48
  49 * DNS EXT: average time to resolve an external DNS name
  50
  51 * DNS INT: average time to resolve a local DNS name
