Filter vs. seperate shapefiles

[Steve Lime]

Kevin: Anything you can do ahead of time will always make things run faster. The question of how much faster is another matter. That is dependent on the number of features and the types of expressions (straight string comparison is much faster). If your site is going to get hammered then even tiny speed improvements may be worth the pre-processing.

Is it better (ie. faster) to have several map layers reference the same
shapefile using FILTER statements to specify the shapes they reference, or
to create several different shapefiles.....one for each class (on/off
control is required for each layer, which is why we are not simply using
different CLASSES).
