Glad to know that your website is still alive. I remember when you started it.
Something here is slowing down your website. it is very possible that the problem is with some of ad network banners.
raw text is loaded first then after some time (up to 30sec) loads CSS and all other stuff on the website. it is very possible that it is up to the directory script which you use there.
In the end, you always can test it, for example https://tools.pingdom.com/#5d24e82561800000
