Hi there.
I've currently implemented some code based upon "simpleclient.cpp" which
is very basic. However, when running through a loop to generate a number
of routes, the memory decreases with each pass resulting in swap file
eventually being brought into the equation. Once that happens,
everything slows down!
The basic bones of my code is shown below:
// Set up the parameters required.
RouteParameters route_parameters;
route_parameters.zoom_level = 18; // no
generalization
route_parameters.print_instructions = false; // turn by
turn instructions
route_parameters.alternate_route = false; // get an
alternate route, too
route_parameters.geometry = false; //
retrieve geometry of route
route_parameters.compression = false; //
polyline encoding
route_parameters.check_sum = -1; // see wiki
route_parameters.service = "viaroute"; // that's
routing
route_parameters.output_format = "json";
route_parameters.jsonp_parameter = ""; // set for jsonp
wrapping
// Start the outer loop.
for(int oLoop = 0; oLoop < 10000; oLoop++)
{
// Start the inner loop.
for(int iLoop = 0; iLoop < 10000; iLoop++)
{
// Clear down the route parameters.
route_parameters.coordinates.clear();
// Start_coordinate
route_parameters.coordinates.emplace_back(latlonPC[oLoop][0] *
COORDINATE_PRECISION, latlonPC[oLoop][1] * COORDINATE_PRECISION);
// Target_coordinate
route_parameters.coordinates.emplace_back(latlonPC[iLoop][0] *
COORDINATE_PRECISION, latlonPC[iLoop][1] * COORDINATE_PRECISION);
// Run the required query.
routing_machine.RunQuery(route_parameters, json_result);
}
}
Not a lot to it, therefore I'm wondering if the memory leak is in the
RunQuery function and if so, how can I minimise the issue.
Kind Regards
James
