Moving this topic to 'Linux Guests', since I doubt that the host has anything to do with your question. You should also consider the configuration of the guest OS, though as I'm not a Linux user I can't help you with that. For example, look at a task monitor and find out exactly where the CPU is going. I won't be able to say much on CPU usage unless you provide evidence on that too. Select 'Show Log' and save 'VBox.log' (ONLY) to a zip file. A VM log file would be useful (with the VM fully shut down, right click it in GUI. I note that you say you did this, but you haven't provided any evidence. If you want improved graphics performance you must enable 3D acceleration, and install the Guest Additions.

Perhaps if you have problems in future you should avoid trying random things, since you'll most likely only make things worse. VT-x has nothing to do with software rendering of video.
