When previewing, why does it always re-process whole work area even when I make a small change?

I just bought a new MacBook Pro and AE CC. I have been using After Effects for decades, however. I don't remember it ever doing this. Do I have a setting wrong?

When I preview my work area by pressing zero on the numeric pad, it calculates and previews fine. However, when I make a slight change, even to the audio track, it reprocesses the whole thing again, even if the part it is reprocessing was not even near the keyframes I was manipulating. Shouldn't that part still be untouched in the buffer? I have tried with draft mode, and fast preview mode.

I'm sure there must be some setting I have wrong???

Thanks in advance,
Ian.

Try purging your memory. Also, check your disk cache allotment.

If the timing is even slightly changed in the video, it has to recalculate. If you put a keyframe at the end, but remove one from the beginning, it has to recalculate also since there is no keyframe where there once was.

If you tweak a layer that's the same duration as the composition, that'll happen. If you tweak a 2-second clip in a 30-second comp, AE only has to think about that 2-second bit.
