other sources http://mapki.com/wiki/Read_This_First#My_map_loads_slowly_when_there_are_1500_markers are talking about a limit at about 200 markers, so this 'might' be a limit on the google side. What I meant by the redundant code was the JavaScript that get's shoved over the net generating the markers. Looking at the example you provide: http://turengaartil.dk/tgt/gmap/ with firebug http://www.getfirebug.com/ one can see that the page with all JavaScript maps graphics and everything is about 145kb big. Clicking the hotel check Box an XMLHttpRequest with an URL like this one goes over the line: http://turengaartil.dk/tgt/gmap/?wicket:interface=:11:formFilter:displayHotel:-1:IUnversionedBehaviorListener&wicket:behaviorId=0&wicket:ignoreIfNotActive=true&random=0.7992635059750802 its response is containing the definitions of the Markers it is 142kb big. The definitions of the markers look very redundant.
