Subj:   Re: Stored Procedures - Cursor Processing
 
From:   Geoffrey Rommel

  Why, oh why, oh why do Stored Procedures perform so appallingly bad in Teradata, when they include Cursor processing ?  


Dieter kinda answered this already, but the main reason is that a SP runs on a single PE. Since that one PE must communicate with all the AMPs, it's never going to?be as fast as an all-AMP process -- not even close.
