Hi Guys,
Would appreciate a little help on the following:
I am looking to compare travel times between one starting point and multiple possible destinations;
For example
SE1 2TH
to
CR0 2RB
SM3 1FT
WC2N 5DU
NW8 9AY
…
…
The possible destinations could be a few hundred;
It doesn’t have to be postcodes - it could be coordinates.
It has to be reasonably fast 
It doesn’t have to be real-time;
How are those guys doing it?
