在Google地图上将鼠标悬停添加10000个地标，在C＃中需要2个小时

Question

I am adding 10000 place mark on google map with hover but it is taking around 2 hour .Which is not good for any user.

Please suggest me what is the idle time taken by the google map and how i can speed up.

I am doing following steps

1) select distinct locations form database for selected person.

2) Make script to add all the locations of salesman.

3) Call google map api(v3) and pass script to it to load all values.

Please suggest

Answer 1

Google Maps wasn't made for handling that many markers at the same time and the speed will be quite horrible. Try to limit the amount of markers placed by grouping them together if there are several near each other until the user zooms in and only load the markers needed for the current visible area.

I'm not really sure how you are displaying this map but my guess is in a webbrowser control? If so, then you could use a helper library such as Marker Clusterer or Marker Manager (both available at http://code.google.com/p/google-maps-utility-library-v3/wiki/Libraries ) to help you out.

I don't know how much this will help you with 10,000 markers, but after a little bit of searching, it looks like there are more efficient ways of managing markers than just dumping them all onto a map:

Based on the benchmarks at the end, it's still going to take a few minutes to load 10,000 markers. Google Maps certainly wasn't designed to handle that many markers at once. The best way to speed things up is to only add the necessary markers. I can't imagine anyone making any sense of 10,000 markers. Narrow it down to only a handful that an end-user can understand and work with.
