Too slow

Posted by gwx-cathy on 19 June 2014 in English (English)

I plan to show OpenStreeMap on a course to college students. But it is too slow to display the map in some minutes. It is really impossible to use it during the course.

Which part are you showing them? Are you using the default website or another tile supplier? Are you connected with DSL or fiber or using a modem? Do you have "Show Data" checked? This will slow viewing the map down - by a lot.

I'm sure given more details we could assist you, I myself have been planning to make a "Starter kit" for teachers in my native country and so am eager to hear of any problems teacher might have with any class interaction with it.

If it is just the online map loading slow you could browse the area you want to show before you present it sou you have the tiles cached. You could also use QLandkarteGT with an OSM-based Garmin map or Routeconverter's experimental branch using mapsforge┬╣ maps. Of course you should download the needed maps before attending the course.

Though it would be helpful if you would mention more clearly what on "the OSM map" is slow or what you try to achieve instead of complaining quite unspecific.

┬╣ Don't be offended by the name, it works on linux, too: or from
