Hello, i ran a test from pingdom to see the loading time of my website... the result is that i have a lot of small files that take a lot of time to load because there is a big delay between the start of the connection and the real downloading of the file (in pingdom tools, this results in a very large green bar). Have a look at this for example: http://tools.pingdom.com/default.asp?url=http://www.giochigratis-online.net/&id=5691308 How can i lower the "green bar" time? Is this cpu-limited, bandwith-limited, or what? Thanks!
I would suggest to use a better tool than pingdom to get a little more info. I personally prefer Firebug within FF but any modern browser has something called "Developer Tools' installed. In Firebug (once you installed the addon), use the Net Tab to profile your website again. Reload your site a couple of times and see if you have delays in on the same file all the time. It might have just been a hiccup. If you do have a problem at that same image, I can only imagine that the server is throttling you maybe based on the number of parallel connections. However, that is just a guess. The file itself is so small, that it should not cause such a long delay.
There are several step that your browser goes through when it loads a webpage. DNS lookup time, TCP connect time and then HTML download time. When you get delays on the initial connection it is because whatever servers are supplying DNS or your website are overloaded (busy). You may want to try to find a better provider. You can do testing from http://www.mysitespeed.com to do further testing if you'd like.
thanks a lot for your useful feedback! I have a lot ot things to work on now, and i'll start with testing the website with these tools you suggested =)
