Page Speed results vs Webmaster Tools Site Performance

[roxer]

When I log into my Google Webmaster Tools account and check on the page speed it tells me 68% of sites are faster than mine



However, when I run Page Speed Test on FireFox / Firebug it reports back in a very positive manner:



I've told GWMT my geographic target is the UK but am left confused thinking they must be spidering me from the US and not taking account the geographics.

In other words, my site is fast as hell but Google say it's slow.

What can I do to convince them it rocks?

How fast is your server? It could also be your server throttling Google bot, so a user it's quick for Google it's slow, there is a firefox tool call usera gent swithcer allows you to load the site pretenting to be the google bot.
