I have more then 8000 markers on a Gmap view, using clusters (markerclusterer.js) , and I have a loading time 16 seconds.
How can this be optimized? The view is cached, Drupal is cached and compressed and running on Pantheon already.
This loading time is caused from the view query to get the markers, as they are all already in the head of the HTML page when the page is loaded.
I was thinking to hardcore the markers into JSON, but still I don't know how it could be intehrated with gmap after.
