in thread Splitting a string to chunks

umhmm you got my typo. i accidentally used $string instead of $str in my post first. that explains the high rates for the regex solution. here is the timing with the typo corrected:
Rate split_pos grep_split substr_map regexo regex subst +r_loop unpack split_pos 5587/s -- -65% -69% -76% -77% + -79% -81% grep_split 15974/s 186% -- -12% -32% -34% + -40% -45% substr_map 18051/s 223% 13% -- -23% -26% + -32% -38% regexo 23474/s 320% 47% 30% -- -3% + -12% -20% regex 24272/s 334% 52% 34% 3% -- + -9% -17% substr_loop 26596/s 376% 66% 47% 13% 10% + -- -9% unpack 29240/s 423% 83% 62% 25% 20% + 10% --
