其实说起来,用std::pmr::monotonic_memory_resource和freelist共同实现一个内存池,这个想法怎么样……我用这个想法加上payload使用std::pmr::unsynchronized_pool_resource能够把C++的时间压缩到4.5s左右。 05-19· 陕西 回复1 脉冲星 李杭帆 ?woc怎么突然翻出来了我记得checksum是没问题的 09-01· 陕西 ...

据我所知,C++中存在与实现相关的C++优化,它允许string不分配任何额外的堆内存来存储其字符,而是将字符存储在string对象本身中。因此,如果字符串s在堆上分配额外的内存,那么它消耗的总内存是sizeof(string) + s.capacity(),但是如果它没有在堆上分配任何额外的内存,即将其字符存储在string对象中,那么总的内存消耗就...

If you specified LOCALE(strinf string literal), the compiler uses the runtime function setlocale(LC_ALL "string literal") to determine the name of the compile-time locale. If you do not use the LOCALE compiler option, the macro is undefined. Prior to z/OS V1R9 XL C/C++, the __...
