I am using a Physcis(chipmunk)

Hi.

I am using a chipmunk.
I have questions.

Why is it slow when moving touch to the joint?
chipmunk C examples are faster movement speed.

my code(cocos2d-x)

PhysicsJointPin* joint = PhysicsJointPin::construct(_boardJoint->getPhysicsBody(), _board->getPhysicsBody(), _boardJoint->getPosition());
getSceneWorld()->addJoint(joint);

= A little slow

chipmunk C example :

			// Use the closest point on the surface if the click is outside of the shape.
			cpVect nearest = (info.distance > 0.0f ? info.point : ChipmunkDemoMouse);

			cpBody *body = cpShapeGetBody(shape);
			mouse_joint = cpPivotJointNew2(mouse_body, body, cpvzero, cpBodyWorldToLocal(body, nearest));
			mouse_joint->maxForce = 50000.0f;
			mouse_joint->errorBias = cpfpow(1.0f - 0.15f, 60.0f);
			cpSpaceAddConstraint(space, mouse_joint);

= QUICK!!

body-> setMass (0.1)
joint-> set MaxForce (9999 ...)
Also set to slow.

Other What I can do?

Thank.
