I know GeoServer is different from OpenLayers, but what I am questioning is how big is that impact on rendering data.<div>I have a development environment on my machine consisting of Apache Tomcat and GeoServer.</div><div>
This same machine is running the Browser that accesses OL code.</div><div><br></div><div>The vector data is hosted on a Oracle server on a different machine.</div><div><br></div><div>I find weird that Geoserver, running on my machine, can retrieve the vector data from Oracle Server, render an image and deliver it to the browser, while the browser itself, can't take the XML and render an image. And it is not a performance issue. It simply consumes all my physical memory (that is something like 4.5+ gb) and FF crashes, without any warning or error logging from OL.</div>
<div><br></div><div>I know that rendering and delivering an image is a lot simpler than building nested divs and image tags, parsing XML, etc. Even more if you compare Java to Javascript. But is it really "4gb+ simple"? That is what I find weird.</div>
<div><br></div><div>I didn't have time to check the rendering code yet, because I am currently working on a project that will serve only WMS images.

<br>Right now I am using MaxResolution to crop the whole Layer if the level of detail is small (i.e. low zoom level).<br>
The weird thing is that GeoServer can serve me the image in real time of the same layer and OL crashes the browser for lack of memory, and both (the browser and the GeoServer) are hosted and running on my development machine. I know OL is javascript, but even though, there shouldn't be such a huge impact on memory.<br>

</div>From the top of my head I remember that you can use the cluster<br>
strategy with other types of geometries than points. However clusters<br>
are always represented as points.<br>
