i am using w3 total cache plugin and it indeed optimized my site.However, my first byte time is very slow...When i visit my website for the first time or a page, it take's 5-8 secs to load but after the page finish loaded and then i reload it again i loads in 2milli secs very fast.
I am not sure if its a cache or dns problem but the issue seems to be slow when a page is visited for the first time...this is my website :http://www.technobezz.com/
