Benchmarking Google Maps

Recently I've been building a JavaScript API which wraps the the Google Maps API for both version 2 and 3. Its coming along very well and I've already unified most of the basic functionality into a simple to use API which is kind of a blend between the two versions.

The other day I was building in the marker support when a thought crossed my mind: "Has Maps 3 improved the rendering time for adding Markers to a Map?"

And so I went about setting up a benchmark to test it. It was a very simple test which uses firebug's profiler to monitor the "addMarker()" function call to add 1000 markers to a map. I performed the test identically in both versions of Maps. And the results? Amazing.

Version	Own Time	Total Time	Avg. Time	Min Time	Max Time
2	13.252ms	14684.619ms	14.685ms	11.756ms	238.471ms
3	9.132ms	287.789ms	0.288ms	0.274ms	0.548ms

Well done Google Maps team!
