Comment (by cgountanis):

 Hey Tom,

 If I was better at C I would try and look at the problem. I realize this
 is open source but with Autodesk as it's big brother. I am sure they want
 to hit ESRI with fast SHP file performance, right?

 I brought the issue up in the user group and many others have same issue
 including tooltips. Your quote "although I am seeing slowdown" should
 prove the issue is in the way the FDO reads the SHP files in one single
 directory. My solution would be when you query unmanaged shp feature
 sources to ignore all other files in directory and hit the one set of
 files only. For example you have 32 shps/layers and you do a zoom on the
 parcel layer. It takes 15 seconds to zoom since there are other shp file
 sin same directory. Is it not an easy fix to just nail the parcel files
 and ignore the rest. You have to specify the layer name when creating the
 resID why not use it?

 What else can I help with?
