| 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 | |
