581 | 15 * "ngx_sprintf(text, "%ud.%ud.%ud.%ud", p[0], p[1], p[2], p[3])", however, |
16 * they had been implemented long before the ngx_sprintf() had appeared | |
461 | 17 * and they are faster by 1.5-2.5 times, so it is worth to keep them. |

19 * By the way, the implementation using ngx_sprintf() is faster by 2.5-3 times | |
479 | 20 * than using FreeBSD libc's snprintf(). |
