Did just this. The result is that both versions perform worse.

--- Repeat x1 ---
dmd -release -noboundscheck -O -inline
Average time: 80 msecs

Average time: 2 msecs

--- Repeat x100 ---
dmd -release -noboundscheck -O -inline
Average time: 78.84 msecs

Average time: 0.08 msecs

asm of dmd = 48,620 lines
asm of lcd2 = 15,524 lines

I can send the code to anyone who would like to test it.
