[cqwrteur@DESKTOP-9B705LH 0001.string_push_back]$ wine ./fast_io_heaprealloc.exe fast_io:0.0202311s 50000005000000 [cqwrteur@DESKTOP-9B705LH 0001.string_push_back]$ wine ./fast_io_noheaprealloc.exe fast_io:0.0169487s 50000005000000 [cqwrteur@DESKTOP-9B705LH 0001.string_push_back]$ wine ./std.exe std:0.0205867s 50000005000000
just significant slow down for unknown reason while on windows it does not have this issue. there is no reason why realloc is slower than malloc + free combo
I did report the same bug before?
