I appreciate the humor :-)
But for the record:
I never assumed or said that there is a bottleneck in his application.
I said that for inclusion in the RTL, the speedup would be needed,
as the RTL is used in all kinds of situations, not only in his application.
Can you, BTW, explain the reference to Knuth ? I know who Donald Knuth is,
but fail to see the link... ? (lack of culture on my part, I assume...)
