Both no problem here, load time approx. 1 or 2 seconds, a short wait and then the site "flashes" into the screen. Nothing to worry about. The are two things which takes quite long:
a) the Google Map on http://vodnar-letral.si
, which shows up in the bottom. But i think you iframed that one, so its not an server issue from your PC.
b) a "ressource" (i did not analyze, what it is) from fcdn*profile***.net (or similar, i think its advertising, I could not read that quick enough), i dont know what it is.
But all in all, its not slow.
The Pingdom Website Speedtest tells me for s-bazeni.si, that its performance grade is 76/100, 66 Requests, 4,18s Load Time and 2,2MB total Page Size. That results in approx. 4-5 Mb/s speed, absolutely Ok for a private server. Anyway, I do not recommend to run Xampp on a private PC, a hosted Webspace is connected by far faster and it is maintained by a professional hoster. You also do not save money with your own PC, as you need lots of power for running your PC 24/7.
