The response of hydraulic systems and servomechanisms can be much quicker than the response of their electrical or other counterparts. This is one of their advantages. For example, a hydraulic motor can accelerate or change its speed more quickly than an electric motor of the same torque rating (mainly because it has a far lower inertia). The response of a high-performance hydraulic system is usually measurable in terms of milliseconds with the permissible degree of oscillation closely restricted.
