Hi,<br><br> I am developing an application with MapServer v2.2.7 with Apache on Windows XP, but I have a serious problem, below I describe it:<br><br>Using Navteq demo maps from Paris, the Streets.shp have around 500000 line strings features, when mapserver renders the layer without using DBF data (only draw lines) everything is OK and fast, but when mapserver needs to access to the DBF to render labels or use expressions to filter data, mapserver starts to consuming 100% CPU and nothing is rendered after to spends a long time.<br>
<br>Using Teleatlas demo maps for a medium city of Spain, the Street.shp with around 11000 line strings features doesn't show any trouble and mapserver renders the images OK and fast even accessing to DBF to render labels<br>
<br>Could somebody help me with this problem? Why does it happen? How do I solve it?<br><br><br>Thank you very much.<br>
