Google maps and Jquery is showing only few points

i am trying to make my custom points in google map (over 2 500 adresses) and google maps is showing only few points. Does anyone knows, where is a problem?

I am sorry for my czech notes in code.

The code is:

Solution

The client geocoder will only work for about 10 addresses before running into the quota/rate limits, geocode your addresses offline and "cache" the results to use when loading your page.

See Geocoding Strategies in the "articles" section of the documentation.
