================================================================================
Kernel modules data:
Check if pcspkr is loaded: Yes, may cause bigger latency.
  can be eliminated using:
  sudo echo "install pcspkr /bin/true" >/etc/modprobe.d/pcspkr.conf
Check if snd modules are loaded: Yes, may cause bigger latency.
  can probably be disabled in bios, alternatively, you can run
   "./block-snd-modules"
   which has just now been created for your convenience.

Preparing for latency test:
Started glxgears No. 1, 2, 3, 4, 5
..........
Started firefox with 'https://vimeo.com/150574260', WID 50331651
