Re: 10,000ths of a radian per second

In space, it's the efficiency that counts. You'll typically have very long periods over which that thrust need be applied. For instance, if you could constantly accelerate something at 1G (around 100N), it would take less than a year to reach the speed of light (relativistic effects aside). With this in mind, the typical thrust of an ion thruster (0.5N apparently) isn't all that bad.
