As to taking 12 minutes to do the EWNS calibration, if its taking 12 minutes instead of 2 to 4 minutes or less, you may need to change the calibration step size. This can also be affected by other settings in PHD, if you post the PHD parameters or screen shots of both the PHD guiding graph and the "Brain" settings page along with your guide scope and OTA information, then I can advise you as to adjusting settings in PHD...

did you completely shut PHD down?
What Guide Camera and guide scope are you using?

The only two parameters in the "Brain" area I would change are the calibration step, I would try settings in the range of 750 to 1500. The second is the Max Dec Duration, "rule of thumb" should be the same or larger than the Max RA Duration. However I do not think any of this is why you are getting long calibration times. Its more likely to be the quality and brightness of the calibration star and the exposure time, brighter is better and shorter exposure times give the best guiding in my experience.
I'd try a different guide star...
