Description
The following test case shows a a precipitous dropoff in the performance in setlocale() on HP-UX (regardless of the hardware architecture, i.e., on both IPF and PA-RISC) between +DD32 and DD64:
On HP-UX 11.31/IPF:
$ cat t.c && aCC t.c && time ./a.out 1000 && aCC +DD64 t.c && time ./a.ou> #include <stdlib.h> #include <locale.h> const char* const locales[] = { "C", "C.iso88591", "C.iso885915", "C.utf8", "univ.utf8", "ar_DZ.arabic8", "ar_DZ.utf8", "ar_SA.arabic8", "ar_SA.iso88596", "zh_CN.hp15CN", "zh_CN.utf8" }; void test () { unsigned i; for (i = 0; i != sizeof locales / sizeof *locales; ++i) setlocale (LC_ALL, locales [i]); } int main (int argc, char *argv[]) { unsigned nloops; nloops = 1 < argc ? strtoul (argv [1], 0, 0) : 10000; while (nloops--) test (); } real 0m0.466s user 0m0.180s sys 0m0.280s real 0m3.620s user 0m1.560s sys 0m2.040s
On HP-UX 11.23/PA:
real 0m1.060s user 0m0.290s sys 0m0.510s real 0m28.550s user 0m16.110s sys 0m11.850s
