I have several servers, with different hardware and different operating system releases (but all Ubuntu based).
I would like to know the difference in performance between those servers, by issuing simple commands. I do not need it to be a very accurate measurement, just a rough estimate. I am specially interested in disk, memory and cpu performance.
Is there a simple way to gather this information?
Usually I would do:
user@server ~ » cat /proc/cpuinfo | grep bogo bogomips : 4265.02 bogomips : 4265.41 bogomips : 4265.40 bogomips : 4265.41 user@server ~ » cat /proc/meminfo | grep MemTotal MemTotal: 4043652 kB
But I would like a bit more info. A small performance test would be very interesting. Is there any tool for that?
For disks we have:
user@server ~ » sudo hdparm -t /dev/mapper/callisto-root /dev/mapper/callisto-root: Timing buffered disk reads: 386 MB in 3.00 seconds = 128.59 MB/sec
