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
|

10

17 * and they are faster by 1.5-2.5 times, so it is worth to keep them.
|

18 *
|
|
|
19 * By the way, the implementation using ngx_sprintf() is faster by 2.5-3 times
|
|
28
|
20 * than using FreeBSD libc's snprintf().
