Situation
We use gmap module to generate gmap and display markers on it. When user click on marker we display popup, it works well if website display 100-200 markers only, however when it gets to 1000++ Drupal can't display such page.
Issue
Issue happens because Drupal exports all required information to display popup directly on page and it takes to much time generate that.
What I've done so far
I googled and did not find anything that could help me. I know that google map API may deal with feed/xml (that's a direction I'm moving to), however I do not wanna create new wheel if it is already exist.
Thanks!
