[GraphHopper] Building Distance Matrix offline

[Giampaolo]

Hi Peter,

thanks for your answer,I managed to build distance and time matrix :)

I have a question about values returned from res.getMillis() : they are
 always lower than the values provided by google maps or bing.

As example , a route of 3,7 Km in the center of Milan city is :

10 Min - GoogleMaps
8 Min - Bing
About 4 Min - my time matrix

these values are referred to routes without traffic.How can I make my
values consistent with those?
