Is the difference between speed testing ...

Is there any difference between the results of testing the speed - if I write for testing different site address?

  1. xxx.com
  2. www.xxx.com
  3. http://xxx.com
  4. http://www.xxx.com

Thank, …

The http:// doesn’t matter but including or not including a www could matter because technically they are different sites. Sometimes you will get a redirect from one to the other (which will add time) and in some rare cases you’ll actually get completely different pages.

Thank you very much Patrick,
after following your advices, my site started to fly, and visitors were added and the Googlу and other search engines works better with our site. Thank you very much Patrick.

It is unbelievable. I’m happy !
