SVRT is the best choice when you've got a clip that PD has a similar output profile for, AND you've only made minimal changes, like trimming it or adding a few titles or transitions. Basically, SVRT copies all of the unchanged frames to the output video, which is very fast and doesn't require any producing.
If there are only a few changed areas in your clip, SVRT will produce them normally which will take some additional time, but overall the clip will be ready faster than if you had produced the entire timeline.
If you will be making lots of changes, like adding many titles or transitions or FX, or doing things like video speed changes, zooming/cropping, using keyframes, etc., SVRT will not be very helpful. Since it uses only the CPU for producing the changed areas, your project may produce faster if you have a GPU card and select that option instead.
The Profile Analyzer tool and enabling the SVRT track in the Edit room will give you an idea of how much of your project SVRT would be able to copy straight to the finished video. Also, not all formats can be processed with SVRT. Some have to be converted and produced even with no timeline changes, like WMV.
