I have changed my site again. I had been using Wordpress for a long, guess it time for change. I am now switched to Ghost. Although I was using light-weight theme in Wordpress and running CloudFlare for CDN goodness, site was very slow sometime.
I had tried Ghost in their hosted site a couple of months back and then the trial period ended. The design and simplicity of Ghost was impressive.
I am using awesome Ghostium theme. I still need tweak and add search and realted post functionality.
