    Very poor performance on oracle linux 6.3 on virtual-box 4.2

      Dear all,

      I installed an oracle linux 6.3 on vbox VM (2 gb RAM, 20 gb disk): the installation took a long time and after, I faced poor performance and big latency.

      One bug reported:
      WARNING: at kernel/time/clockevents.c:47 clockevent_delta2ns+0x79/0x90()

      I upgraded memory to 4 gb RAM but it was on vain

      Please, any idea so far ?
      Best Regards
