comment Generating a routing database for the entire world while keeping the tags
If you need the road network only (no footways, tracks, etc.) tileSize=30x30,1.0,c should do it as well, but a lot faster. Even 45x45,1,c might work, but drives osm2po's to its limit. And... use c

Please read current on-screen help on the web page and look for tileSize. Furthermore look at this interesting discussion: gis.stackexchange.com/questions/57242/…

comment How to get the public transportation in Osm2po?
What kind of transportation are you going to include? Think of OSM's weird tagging here and read the Wiki first. You'll recognize that it's not that easy. Nevertheless, for a first impression you can set osm2po's wtr.finalMask=rail instead of car.

You may also send the log file to my info@-addi.

Is the message itself correct? I mean, does the file actually not exist?

comment pgRouting 2.0 slow execution of A star algorithm
looks like a heuristic based on the Manhattan-Distance. If not, the data must be projected somewhere before. Nevertheless, I would have expected a distance calculation. Some Euklidian function or sth. like that.

comment Osm2po : Querying generated table to get the closet line from a point
Do you use an index for geom_way? Have a look into the created sql-file (last line). There you will find sth. like this here: -- CREATE INDEX idx_hh_2po_4pgr_geom_way ON hh_2po_4pgr USING GIST (geom_way GIST_GEOMETRY_OPS); And it's a good idea to use a bounding-box around your points. Nevertheless this question rather belongs to the postGIS area.

The heuristic looks very strange.

comment pgRouting 2.0 slow execution of A star algorithm
Are you sure that (|dx|+|dy|)/2 is the heuristic? This seems strange. What are dx, dy? The heuristic must be added somewhere to the costs before inserted into the PQ.

comment How to configure osm2po to use the specified maxCost in TspDefaultMatrix
well, "never" is only an assumtion. Would rather say in 99,9% of all cases.
