We have a petition and each petition signature goes on a google map as a flag.

The problem is that we now have 3000+ signatures (and rising by hundreds each day) and so the html is becoming huge.

So I'm going to change it to an AJAX script. Would it be better to ajax in all 3000+ signatures at once in one AJAX query or would it be better to run 3000 separate queries?

I have a feeling that the answer could be the second one, but however what impact will it have running 3000+ (almost) concurrent ajax queries on the server?

Thanks guys.
