Hi all,

I have several very large shapefiles that I wish to display.  =
Everything
works fine, except that rending and querying take a _long_ time.  Does
MapServer work with attribute indexes on shapefiles to speed up =
queries?
Spatial indexes to speed up queries?  I have read about the TILEINDEX =
but am
not sure how this applies to a single large shapefile.

Any help would be appreciated!

Thanks,
