DESCRIPTION
Tries to gather some CPU/hard disk performance data on the hard disk mounted at PATH (/ is used as default):
- CPU BOGOMIPS
-
bogomips sum of all CPUs
- REGEX/SECOND
-
regular expressions per second (perl performance test), should be above 300000
- HD SIZE
-
hard disk 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.
- 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
