iconset column evaluation too slow

Feb 1, 2009 at 2:45 PM
If i insert at least one iconst column into a WSS list, all the list views which include the iconset column into the selected column list for display, become very, very slow.
As much iconset column you define as much slow the related view become.
Just to clarify,  in my WSS site I have a custom list with non more than 50 elements.
When I activate the standar Allitems view it needs non more than 2/3 seconds to display the first 20 elements.
If I define iconset columns into the list  without referencing them into the view the response time does not change.
If I include one iconset column into the view the response time increse at 8/10 seconds, and more iconset columns I add to the view, more higher become the response time.
Which is the reason why of this site effects? It is embedded into the assembly used to calculate the formula?
Have you any suggestions?

In order to accelerate a bit the calculation for the current release you might want to use this trick described here as concept http://stefancostan.blogspot.com/2009/01/running-ajax-within-sharepoint-list.html and here as how is applyed to IconSet: http://sharepointfiesta.blogspot.com/2009/01/iconset-and-ajax.html.

I know the actual release has some performance issues, I will try to fix them in the future.
