Need a consultation - Slow initial page display

[histerius]

Test from Europe, Windows 7, Chrome, first open almost instantly. After the home page, other pages are rendered after ~2 sec waiting. Looking at the graph, there are several js files, maybe they can be combined into one, fonts are taking relatively long time do download, there are many icons but they are loading fast. I'm not expert for WordPress but maybe several css files and the theme are the reason for waiting before rendering.
