This tool tries to gather some CPU/Hardisk performance data on the hardisk (mounted at path).
-
CPU BOGOMIPS: bogomips sum of all CPUs
-
REGEX/SECOND: regular expressions per second (perl performance test), should be above 300000
-
HD SIZE: harddisk size
-
BUFFERED READS: simple HD read test. Modern HDs should reach at least 40 MB/sec
-
AVERAGE SEEK TIME: tests average seek time. Fast SCSI HDs reach values < 8 milliseconds. Common IDE/SATA disks get values from 15 to 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 backed cache (BBWC)).
-
DNS EXT: average time to resolve an external DNS name
-
DNS INT: average time to resolve a local DNS name
