<DIV>Here is some more detail on this dataset:</DIV>
<DIV> </DIV>
<DIV>I am currently displaying two layers, one a layer of polygons on the</DIV>
<DIV>water layer and one a layer of points of officially named features in our</DIV>
<DIV>province. Both are SHAPE files on disk, the water polygons have 4821</DIV>
<DIV>features while the geo names have 16210 features which extend far,</DIV>
<DIV>far beyond the limits of the water polygons. I am trying to attach the</DIV>
<DIV>names to water polygons and checking them so I am viewing them</DIV>
<DIV>together.</DIV>
<DIV> </DIV>
<DIV>When I select a row from the table of the geo names and try to zoom</DIV>
<DIV>to it using the tool QGIS goes into limbo and never does get to the</DIV>
<DIV>location. This is awful performance. However when I select a row from</DIV>
<DIV>the water polygon table and zoom to it then it goes there without a</DIV>
<DIV>problem. I really didn't want to 'window out' the geo names for the</DIV>
<DIV>area that I am working in but out of desperation I will try that next.</DIV>
<DIV> </DIV>
<DIV>Another interesting aspect of these layers is my background layer</DIV>
<DIV>for the water layer which is a layer of polygons of the spaces</DIV>
<DIV>between the map edges, water polygons and rivers. The display</DIV>
<DIV>of this layer causes a sudden performance drop in QGIS, a draw</DIV>
<DIV>goes from 3 seconds to 20 seconds.</DIV>
