<FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>Hi,<BR>
<BR>
We've developed a location-based services solution that uses a commercial map server, java-based middleware for searching our streets and points of interest database, and a javascript client-side API for map presentation and interactivity.<BR>
<BR>
The maps are currently served as single raster tiles, unfortunately we've run into performance issues with the map server software - on a dual xeon server we can achieve a maximum throughput of only about 80 maps / minute. As you might imagine scaling out this solution would be prohibitively expensive.<BR>
<BR>
We'd like to explore using a raster tile based approach and ka-Map looks like a great fit.<BR>
<BR>
I'm interested in getting a rough idea of what kind of hardware/software configuration we would need to support a ka-Map site with the following characteristics:<BR>
<BR>
- Up to 1000 concurrent users<BR>
- Map data in vector format in an Oracle Spatial database and consisting of street level and point of interest data for the entire New Zealand region<BR>
- Responsive map panning and zooming (presumably pre-caching the image tiles would be a good idea)<BR>
<BR>
Any comments much appreciated.<BR>
<BR>
Kind regards<BR>
