This is my take on the processor buffer. The kind of "latency" the processor buffer affects is the responsiveness of the audio engine itself. If moving a volume fader using the large processor buffer, a small amount of lag can be noticed between the move and actual volume change. Theoretically one should see less CPU overloads with the processor buffer set to large, at the expense of the sequencer feeling slightly less responsive. HW
