Hi Steve,<div><br></div><div>Thanks for your reply. However, most of my datasources are vector data. I've created a spatial index on the shapefiles, but with 4 000 000 features it still takes a long time to load everything.</div>
<div><br></div><div>Should I increase ram, or cpu? or Both? the machines have 8 GB ram atm. I'm not sure what mapserver needs in heavy configurations.<br><br>Besides the page on <a href="http://mapserver.org">mapserver.org</a> i dont find much on improving performance for load intensive systems.</div>

your configuration (scale dependent layers w/things like reduced resolution layers where possible). -Steve<u></u><u></u></span></p>
