--- Comment #18 from Ondrej Vasik <ovasik(a)redhat.com> ---
It turned out that cut field is actually the only one scenario which could be
reasonably easily improved.

- closing RAWHIDE, as we don't plan any other multibyte handling performance
improvements in coreutils in near future.
Here are results of my testing:
(input file 3M4, 100k lines with 6 columns (each column with word beginning
with F)
Old package: cut -f3 mytestfile >/dev/null -> time : 0.223s
New package: cut -f3 mytestfile >/dev/null -> time : 0.029s
Old package: cut -d'F' -f3- mytestfile >/dev/null -> time : 0.264s
New package: cut -d'F' -f3- mytestfile >/dev/null -> time : 0.032s
