------- Additional Comments From joerg dot richter at pdv-fs dot de 2005-01-27 15:05 ------- With patch draft_19642_3 and count=1000000
$ time t > /dev/null real 0,64 user 0,60 sys 0,01 $ time t cout > /dev/null real 1,14 user 1,12 sys 0,00 Now its only 2 times slower than sprintf. Much better than the ~75 times before. Also note, that when an other locale than "C" is in place the times also get better: without patch: (count=100000) real 28,27 user 6,34 sys 21,87 with: real 5,66 user 1,89 sys 3,78 (sprintf:0,07s) This case is still horrible slow, but 4-5 times better than before. Good work so far, but I think the final solution is to avoid any frequent setlocale() calls. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19642
