I’m building a website using a WordPress theme The Travel Theme (http://thetraveltheme.com/). The problem is that the website is loading really slowly. Let me explain – after the initial HTTP request, it takes seven seconds to send other requests. See the picture.

Since it happens on my website as well as on the official theme website using this theme, it’s most likely theme-related problem. It shouldn’t be caused by plugins. I was thinking maybe it tries to connect somewhere and the connection times out after seven seconds, but I can’t figure out more.
I contacted the theme developers, but no reply so far.
Do you have any idea what might cause it and where to look for a problem?
The issue was resolved by Simon here.
„There are external calls to a webserver in Australia to fetch these advertisment urls and these calls block the whole theme.
So if you want a quick and dirty solution to avoid these delays just comment the codeblock in the
footer.phpfile in the root of the theme.Everything in the
divelementfooter_bottombut not this part in the beginning:This should give an performance boost +90% for the inital connect and +60% for the complete site (depending on different factors). Of course there are many other ways to improve the performance but this one should make the situation acceptable for the moment.“ (Simon)
I hope this helps other guys using The Travel Theme.
