23 pmgperf - Proxmox Simple Performance Benchmark
24 ==============================================
28 The command line tool `pmgperf` gathers some general
29 performance data. This is mostly useful for debugging and identifying
30 performance bottlenecks. It computes the following metrics:
33 CPU BOGOMIPS:: bogomips sum of all CPUs
35 REGEX/SECOND:: regular expressions per second (perl performance
36 test), should be above 1000000.
38 HD SIZE:: harddisk size
40 BUFFERED READS:: simple HD read test. Modern HDs should reach at
43 AVERAGE SEEK TIME:: tests average seek time. Fast SCSI HDs reach
44 values < 8 milliseconds. Common IDE/SATA disks get values from 15 to
45 20 ms. SSD seek times should be below 1ms.
47 FSYNCS/SECOND:: value should be greater than 200 (you should enable
48 'write back' cache mode on you RAID controller - needs a battery
51 DNS EXT:: average time to resolve an external DNS name
53 DNS INT:: average time to resolve a local DNS name
55 Here is an example output generated by the tool:
59 CPU BOGOMIPS: 16759.60
61 HD SIZE: 60.78 GB (/dev/sda1)
62 BUFFERED READS: 209.84 MB/sec
63 AVERAGE SEEK TIME: 1.24 ms
64 FSYNCS/SECOND: 2198.79
66 DNS INT: 1.41 ms (yourdomain.tld)
