based on my experiences it is really a good call setup time
what else you can check is the TN delay on Iub and IU to reduce the delay but belive me less than 2 sec is far good to spend your time on TN delay... others are normall messaging flow which causes delay
anyway it is good to compare call setup time of CSFB with the user who camped on 3G and establishes call on 3G I don't think you will see a big difference
cheers
