as my title says, I have problems regarding the loading time of my website.
If I visit it as a guest, it's very fast but when I try to do the same loggin-in, I notice a very long time increase in the loading of the webpage. This happens to EVERY page on my Joomla website, I use K2, Jotcache and JCH Optimize. I also use Cloudflare as a CDN.
My website is http://sbenny.com
In my opinion, it looks like the website is not cached for registered Users but I'm not sure about it. If this is what's really happening, is there a way to prevent this? If not, what else should I try? I'm actually on a Shared Hosting Service but it's quite fast (less than 0.7s to completely render a webpage for guests)
Thank you for your time.
