I don't see this as an option in the API docs, so I was trying to extend FeatureLayer and override updateLayers() or something to try and remove the GlowFilter, but can't figure it out. I need to optimize selecting thousands of points and lines, and I think the added GlowFilter is adding my overhead. Clustering isn't an option for the data type being represented.
Any tips? I could go back to using a GraphicLayer, but I'd need to do a lot of rewrites to replicate the relationship queries I am doing.
