ODBC is main reason for slow performance. This problem will be solved yb
the time, every version of MG is better.

Subject: [mapguide-users] Polygon selection performance


I am having some performance issues on a relatively simple layer, and I
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
feature class is displayed on the layer.  The problem is, selecting even
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
even though I have fewer polygons.  Is there anything I could tweak to
it better?
