I'm using virtual box to run Ubuntu 16.04 LTS. The problem is that the vm runs slow. I've read a lot of guides to improve it's performence, but nothing worked so far.
My computer details: Processor: Intel(R) Core(TM) i5-6200U CPU @2.30GHz, Ram: 12 Gb, 64 bit.
I've allocated 2 cores out of 4 to the machine, and about 9 GB of RAM, and it still works slow. By slow I mean that when I type, the machine recognizes the typing after about 5 seconds, most of the time. In addition, even when I run the vm, the original windows works fine and quick, so i suspect that the vm dosen't use the whole power it can get.
The virtualization in the BIOS was already enabled.
What can I do?
