Okay, I'm just wondering if there are some people here that have a webmaster tools account (google). (If not you should.)
When you go under labs>site performance ... it tells you the speeds of various pages, along with your total average speed.
Now if I check my site using a variety of different speed testing tools, my site (index page) appears to load in less than five seconds every time.
I use a few tools including: pingdom.com/tools - My site pages usually load around 3 - 5 seconds.
However, according to Google (which I have been tracking now for a long time), my index page usually takes between 9 and 11 seconds, and my overall average for my site is usually around 10/11 seconds. This means (according to Google) that my site is slower than 95% of other websites.
Why this discrepancy? Can anybody else share their results here?
