Performance of transitions?

I got a question about the built-in transitions -are they faster than coding the animations manually? I am asking because I’d need to animate many objects at once, so I wonder if it would be faster either to use the built-in transitions or to code my own animation routines.

Are the built-in transitions designed for best speed and performance or just for “convenience”? [import]uid: 9644 topic_id: 2541 reply_id: 302541[/import]
