DESCRIPTION
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:
|
CPU BOGOMIPS
|
bogomips sum of all CPUs |
|
REGEX/SECOND
|
regular expressions per second (perl performance test), should be above 1000000. |
|
HD SIZE
|
hard disk size |
|
BUFFERED READS
|
simple HD read test. Modern HDs should reach at least 100 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 |
Here is an example of the output generated by the tool:
# pmgperf CPU BOGOMIPS: 16759.60 REGEX/SECOND: 1186304 HD SIZE: 60.78 GB (/dev/sda1) BUFFERED READS: 209.84 MB/sec AVERAGE SEEK TIME: 1.24 ms FSYNCS/SECOND: 2198.79 DNS EXT: 35.69 ms DNS INT: 1.41 ms (yourdomain.tld)
