<p class="MsoNormal" style="">Hello, </p>
<p class="MsoNormal" style="">I am following up on this posting as i am still having this issue. I was it is possible to speed up openlayers without using a tileCache. My test page is only working with three layers and yet it is fairly slow compared to loading
the same data through a Flex viewer (that also doesn’t use a cache). I am sure it is just a matter of a config parameter I am not setting correction. Here is my js when loading the layer:</p>
