Top Assembly 'Too Slow' with flexible Sub-Assemblies

In this particular assembly that i am working on i think itis too slow to move the flexible assemblies. When i try to move apart of a flexible assembly i must click and hold to first engagethe movement of the part, then i have the freedom to move the partwithin its constraints.
My problem is it takes 10 to 15 seconds for the part to engage themovement. When i release the mouse button and click on the partagain to move it(or any other part for that matter), it takesanother 10-15 seconds to move it.

This assembly does have approx 8 flexible assemblies.

Do i need a better system or to change current options for this towork smoothly?
