On pingdom it's loading under 2 seconds.

Pingdom is an uptime monitoring service. While its load time features are helpful, they are by no means representative of what your users are experiencing. The Pingdom probe servers are located in datacenters, where connections are much faster, and physically closer to the major internet exchanges, than what your users have at home. To illustrate: if Pingdom pings my server from the country it is located in, the RTT is a mere 2ms (a bit like pinging localhost). Not even people with a fiber-optic cable connection will see that kind of latency. If you are going cross-country, or even cross-continent, expect those figures to be much higher, especially in countries where internet connections tend to be slower. And the heavier your site is, the bigger the effect of that latency will be, as resources travel to and fro in small packets. For a more accurate simulation or tracking of page load times, have a look at [webpagetest.org ] (simulation) and [torbit.com ] (tracking).

The figures in WMT are therefore more likely to be accurate, because they represent real users' load times.
