I recently just started using virtualbox on my mac machine and the performance is very slow on windows 10. My macbook is fairly new and has 16GB of RAM so not too sure if my configuration is wrong, or what could be causing my virtual machine to experience slow performance. Also in the activity monitor, virtualbox is using 200% of my CPU.Host:

I just installed the fresh copy of Windows 10 so any help would be appreciated. I would need this virtual machine to run an environment for a project using visual studio 2017. 
I have attached my log, hopefully I can get some guidance to see if there is anything else I need to do to my configuration.
