Utterly clueless babble, as always from babblebot.
There is no such thing as a 100% speed improvement ceiling.
It may be any value, depending on what the burst speed of your interface is,
including more than 100%.
The only thing that you can say about it with some degree of certainty
is that it is likely twice the benefit that you get from 8MB cache.
Could be twice the number of cache segments or the same number of segments
twice as big or anything in between.
