Long wait for initial load of this site

Thanks for the explanation about the paint performance. I don't know what is happening behind the scenes, but it feels like it is not in the paint phase yet. At least on mobile there is a progress bar of a site loading in Chrome (blue line filling up from left to right). This line doesn't appear for 15-20+ seconds and it is just a blank browser window. Btw, i do not use internal RSS view, when i press the link it always loads the article in external browser. When i go to to Feedly directly occasionally it seems that text is loading instantly for the articles there. It is a weird delay. As if browser is waiting for something before even loading and rendering the page. When it does start to load the page, rendering is pretty fast. For the text and inline images. Hero images (the big images at the top) do take a few more seconds to load. Although it is not like it is rendering and image line by line, it shows an animation of loading and then image appears instantly.
