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()

Hardware name: VirtualBox

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

Please, any idea so far ?
Best Regards
