[pve-devel] [PATCH v2 docs] add pveperf section and man page

[Fabian Grünbichler]

this is a bit ugly, because pveperf is not an instance of
PVE::CLIHandler - the actual installed man page is still
generated via the pod data contained in
pve-manager/bin/pveperf ...

+Simple Performance Overview
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+On an installed {pve} system, you can run the included `pveperf` script
+to obtain an overview of the CPU and hard disk performance.
+
+NOTE: this is just a very quick and general benchmark. More detailed tests
+are recommended, especially regarding the I/O performance of your system.

 Supported web browsers for accessing the web interface
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 To use the web interface you need a modern browser, this includes:

+=====================================
+include::attributes.txt[]
+endif::manvolnum[]
+
+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
