这次使用的内存池是原公司的，利用hash_map做的，大概的接口是这样：

template 
     
      class ObjectPool{ public:     typedef hash_map
      
        BlockMap;    virtual int pop(CObject *&ob);    virtual int push(const CObject *ob); private:     BlockMap _block_map;};
      
     

写测试代码比较了一下内存池和tcmalloc的差距！结果挺让人吃惊！

#define MAX_SIZE 50000struct MsgToPut{	 UINT _wr_ptr;	 UINT _rd_ptr;	 UINT _length;	 CHAR _base[1024];	 void reset()	 {		 this->_rd_ptr = this->_wr_ptr = 0;		 this->_length = 1024;	 }};ObjectPool
     
       MsgPool;void* newthread(void* argv){	long long int start = get_os_system_time();	for(int i=0;i
      
       reset();	}	start = get_os_system_time();	printf("newthread tc malloc :%d\n",start - end);	return (void*)0;}int main(){	pthread_t pid;	pthread_create(&pid,NULL,newthread,NULL);	pthread_create(&pid,NULL,newthread,NULL);	pthread_create(&pid,NULL,newthread,NULL);	long long int start = get_os_system_time();	for(int i=0;i
       
        reset();	}	start = get_os_system_time();	printf("main tc malloc :%d\n",start - end);	return 0;}
       
      
     

普遍打印数据为：

newthread ObjectPool:189

newthread ObjectPool:202

newthread tc malloc :24

newthread tc malloc :20

main ObjectPool:235

newthread ObjectPool:235

main tc malloc :21

newthread tc malloc :22
