I have different models, which needs to be animated differently. And i do required multiple mixers and clips as well.  
But when I loop over the mixers and call the `update` function, the speed is normal when there is one object or mixer. But as soon as the second or third object or mixer is added, the animation clips’s speed is faster.

What could be the issue here?

what value are you passing into each mixers update?  
Show some code demonstrating how you decide those values when using multiple mixers.
