In the preference, under Global settings, you will see a section called Frame Format. This is were you set your default speed for new comps. You will also see individual comps that are open, and you can override those values for just that comp.
No matter what you view, once cached will now playback at that speed.
Note: this is playback, not render (which doesn't matter for outputting frames)
However, if you are rendering to a codec, you will have to set the speed of desired playback in the format tab of the saver.
