[mapguide-users] Polygon selection performance

[Jon Rizzo]

Hello,

I am having some performance issues on a relatively simple layer, and I was
wondering if anybody might know of a way to easy my pain.  The original
source of the layer is a 400k SDF file, which contains approximately 120
polygons.  These polygons are joined against an ODBC table and the joined
feature class is displayed on the layer.  The problem is, selecting even a
single polygon takes 4 to 5 seconds.  Needless to say, it makes my site
quite frustrating to use.  I would be happy if the performance were
comparable to that of the Sheboygan sample, but it is considerably slower
even though I have fewer polygons.  Is there anything I could tweak to make
it better?

Jon
