With this release the OSRM measure is extended to improve performance making parallel calls to the OSRM server. The faster request-response times are possible by splitting the distance/duration matrix and executing the resulting sub-requests in parallel. The scalability of this technique depends on the resources available to the OSRM server. For this reason a new argument is introduced when creating a new OSRM client that defines how many parallel calls should be made. There are three different options:

• If a value smaller than 1 is given, the number of parallel calls will be chosen automatically.
• If 1 is given, one call is made to the server.
• If a value greater than 1 is given, that number of calls is made to the server.

cli := osrm.DefaultClient("<your-host>", true)
osrm.DistanceDurationMatrices(cli, points)
