I have two VMs running Linux. One seems slower than the other.

Is there a tool which does a general benchmark of the VM?

Things I want to check:

  • Single CPU speed
  • CPU speed of several processes
  • RAM speed
  • Disk speed (sequential) read/write
  • Disk speed (random access) read/write
  • Speed of /dev/urandom (we already had issues here)

It would be great if the tool could create chars which show the results of both VMs in one chart. But that's optional. If I have the numbers, I can create charts myself.


  • runs on linux
  • open source
  • GUI is not needed. Numbers are enough.
  • executing the benchmark should not need more than three minutes.
