Very slow performance, especially screen refresh in Virtual Box

I just installed Fedora 20 in a Virtual Box VM on a Windows 7 x64 laptop host with a quad core i-7, 16GB RAM. The VM has 2GB RAM assigned with 2 processors assigned. I would have expected this VM to be a screamer. I have similarly configured Windows Server 2012 and Windows 8 VMs that run very well on this hardware.

The Fedora VM just drags and is sluggish. What's worse is that it is very slow in screen refresh. If I click something on an app, the rest of the screen responds reasonably, even if slowly, but right under the cursor will not refresh to show whatever is changed for up to 10 seconds.

I have high confidence in Fedora so I'm just looking for what I can do to increase the performance.

Thanks,

Dale

I had already maxed out video memory and had checked the 3D box. Thanks.

Is any one else experiencing similar issues?

I am experiencing slow performance; slow enough that development in Eclipse looks impractical; and that is what I need to do
