New Post: Performance Limits for SPCascadeDropdowns

Hey there,

I'm using SPCascadeDropdowns to create Cascaded dropdowns between two columns. The parent column has about 10 items, but the child column has 1400. This results in the edit/new item form taking about 80secs to load as the SPCascadeDropdowns methods are called on the dropdowns.

Common sense tells me that having a massive dropdown like that is the obvious culprit for such poor performance. I searched for any documentation that indicated recommended limits to the size of dropdowns but couldn't find anything.

Are there recommendations to dropdown size? Any way around this performance hit?

Thanks
R
