Hi Andrew,<br><br>hehe yes or no answer ;)<br><br>What you are doing here is not a "true" comparison of the three different technologies.<br><br>Your mapfish and your openlayers application are using tiles where your fusion app is not. You see in a tiled mapwindow tiles outside of the mapwindow can be cached so that they display when they are dragged into position. Another consideration about tiled mapviewers is the size of each tile.<br>
<br>If the size of the tile requested from the server is requested at the same native size of the tile on the server then the server does not need to stitch tiles together.<br><br>All three of these examples are using Openlayers. So from a strictly fetching of the map image and presenting it on the screen the performance would be identical as long as the requested image is the same size across all three.<br>
<br>And lastly, Your Openlayers app is using Google's Server Farm directly for it's imagery where the mapfish and fusion are requesting it. so it's an extra step for every map draw.<br><br>Fusion is a toolkit that provides common set of map "widgets" and UI controls that enable rapid application development (RAD) there's a buzz wo from the past. :)<br>
<br>If you really want fusion to preform in the same fashion that your openlayers app is. You can:<br><br>Add the OpenLayers.Layers.Google class to your openlayers.js and get fusion to work with it. ( may or may not be an easy task)<br>
Or wait for it to be added eventually ;)<br><br>Cheers<br><br>Paul D. <br><br><div class="gmail_quote">On Wed, Oct 29, 2008 at 5:47 PM, Andrew Parker <span dir="ltr"><<a href="mailto:andrew@source3.com">andrew@source3.com</a>></span> wrote:<br>

<br>
For example, it would be great if I could make my current Fusion application (<a href="http://216.93.173.156/testing/" target="_blank">http://216.93.173.156/testing/</a>) draw the map as fast as my current OpenLayers application (http//:<a href="http://webgis.source3.com" target="_blank">webgis.source3.com</a>) and my MapFish test at (http://<a href="http://216.93.173.156/MFtest/" target="_blank">http://216.93.173.156/MFtest/</a>).<br>
<br>
What I am using for a comparison is the Topo Map Layer with the USGS wells (the data is limited to New Mexico, USA) at a scale of about 1:100,000. When I zoom and pan, I like how fast OpenLayers/MapFish redraws. <br>
I went ahead and turned on the two layers that I am using for a comparison in MapFish test and my Fusion test.<br>
<br>
The topo is from TerraServer. The USGS data is in PostGIS.<br>
<br>
thanks,<br>
