If you have a web hosting in your own country borders. Your web sites will usually very fast load and you feel fastness. But if you had to buy your web server other continents like me you'll have to sufer from few seconds loss. If you have many images to upload then it becomes a really long cycle to finish. For this reason be very carefull to find out the location of the web hosting. You can simply ask this to the web hosting company. Or you can try below.

If you use XP try to run.
RUN this Command and use this at DOS enviroment

ping webhostingcompanayadress.com -t

It'll return you usually a mili seconds. and if it's lover than 100ms we can say web hosting is fast
-t provides continous pinging.
You can compare web hosting companies by using same trick.

You can do also whois.sc/webhostingcompany.com ->it will lead you the location and more datas regarding the web hosting company.
