Image ready - help on saving!

Hello everyone!
I've got a question for you.

I just got Image Ready, and i've used Animation Shop before and I've got a problem.
I created an animation, and in IR it looked okay, until I saved it as a gif - optimized.
I've checked on it and it SLOWED DOWN terribly.



before i saved it, it was going a half more fast than now.
+ is it possible to save animation in PS CS??

thank you everyone in advance!
