Try to post the output of top of your 3 nodes in http://paste.openstack.org/ or other similar website and share the output here. To extract the output of top and sava it in a file you can use the command top -n 1 > top-output.txt

You need more power in your computer. Yes, it will run but as you see, performance is limited. If you can up your memory to 8GB, you should see better performance.

I recommend opening up Chrome or Firefox, head over to your horizon dashboard and hit F12 to start developer mode. Then hit the Network tab and review at what step it's actually hanging at once you've logged in and start changing tabs. This may give you a better idea of what is taking so long.
