It's no longer quadratic in so many cases, but it's still true that UTF-8 string operations require, in the best case, several CPU cycles per character consumed, even when the input is an ASCII subset. LC_ALL=C pretty much guarantees one or fewer CPU cycles per input character. Basics like strlen and strchr and strstr are significantly faster in "C" locale. |
