Benchmark distance matrix calculation

We need some measurement data about distance calculation using GraphHopper to be able to:

• Have a clear idea about the time it takes to calculate the complete matrix for common number of visits (like 100 and 1000).
• Compare the embedded GraphHopper approach to other options.
• Have a baseline to compare against when trying different modes, doing optimizations etc.

Measurement matrix

Axis 1: location count

• 100
• 1000

Axis2: CPU core count

• 1
• 2
• 4

Answer the questions:

• How long does it take to calculate N*N matrix?
• How long does it take to add an N+1st location?
