You mean running Gosmore as a service and interface with it through e.g. pipes? That could mean some speed boost, but I'm using PHP to interface with Gosmore and spawn a new process for each request without serious impact, see: <http://trac.openstreetmap.org/browser/applications/routing/yours/trunk/www/api/dev/gosmore.php> Spawning Gosmore doesn't take that much time. > Updating the database weekly might not be able to meet people > expectation like the instant rendering that we have. > It is more than just a tab to add. Yeah well, our gazetteer isn't updated instantly either, not even weekly. Also, I would be seriously impressed if someone could come up with a routing engine that can have it's database updated in situ and still be able to service the whole world with a performance that doesn't drive everyone away instantly. Please tell me if you know of such an opensource routing engine. _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
