+The command-line tool `pmgperf` gathers some general
performance data. This is mostly useful for debugging and identifying
performance bottlenecks. It computes the following metrics:
REGEX/SECOND:: regular expressions per second (perl performance
test), should be above 1000000.
-HD SIZE:: harddisk size
+HD SIZE:: hard disk size
BUFFERED READS:: simple HD read test. Modern HDs should reach at
least 100 MB/sec
20 ms. SSD seek times should be below 1ms.
FSYNCS/SECOND:: value should be greater than 200 (you should enable
-'write back' cache mode on you RAID controller - needs a battery
+'write-back' cache mode on you RAID controller - needs a battery
backed cache (BBWC)).
DNS EXT:: average time to resolve an external DNS name
DNS INT:: average time to resolve a local DNS name
