I could not make the D program come close to wc's performance when the data was piped from stdin. A typical run with Daniel Kozak's program:$ time cat deleteme.txt | wc -l 5062176 real 0m0.086s user 0m0.068s sys 0m0.048s $ time cat deleteme.txt | ./deneme 5062176 real 0m0.174s user 0m0.152s sys 0m0.072s Ali
How do you compile it? When I use ldc2 -O3 -release -mcpu=bdver1 lc.d my code is even faster than wc
