John, I played with your samples for a bit, and didn't see a large speed difference (running Google Chrome & Firefox 3), but I did notice a definite 'blink' when drawing under the newer API, as the titles would disappear for a fraction of a second before redrawing. This was not reproduced on the older API.
Hope it helps some. -Mike Ethetton Master Toolworks, LLC On May 28, 2:13 pm, John <[email protected]> wrote: > I have developed a web application for the FAA using Google Maps API > to display a variety of data that we are processing here for the WAAS > System. > > One of the features of the map is the ability to display different > contour levels which are displayed by creating a series of GPolygon > objects. > > I have noticed as time has gone on that the drawing of these polygons > has been taking more and more time - to the point now where the latest > version is actually taking a noticeable amount of time to redraw the > polygons. > > To illustrate this problem I have created two different websites. > Both sites are using the same exact javascript files that I wrote to > manage and display the data, the only difference is the API Version > being loaded in the -script- tag in the HTML document. > > Google Maps Version 2.140http://www.nstb.tc.faa.gov/sms14.html > > Google Maps Version 2.159http://www.nstb.tc.faa.gov/sms159.html > > To demonstrate how the polygon redrawing has slowed down - click on > the 'real-time' button on the upper right hand corner and start > clicking on some layers that draw Polygons (RNP 0.3, RNP 0.1, LVNAV, > LPV, LPV200).
