Simple Animation showing as ~6.3 in Xcode console profiler

Hi, I've got a simple animated spring jump that is also a rigid body. When a user lands on it (collides with the top) it animates so as to flick the character (also a rigid body) high up in the air.

It's showing as 6.3 in the Xcode console profiler when activated and I was wondering if this is an expected length of time to be spending on this animation? It's only a simple rotation of a rigidbody (124 tris, 172 verts) - should it really be take this long? It noticeably slows on anything earlier than an iPhone 4.

Is it possible to improve this somehow? And is it normal to take this long? Thanks.
