It's not just one parameter to tune here. It is a set of parameters that 
all together need to be viewed as a whole. The slowdown will be affected 
by the other parameters as well, so turning the millisecond knob only is 
not even half of the story.

Setting the delay to zero simply disables the whole feature at runtime. 
That is why this discussion was using the delay parameter as a synonym 
for enabling/disabling the feature by default.
