c++客户端套接字同时连接

你好，我有一个客户端套接字应用程序，与此同时，在linux中使用tcpip连接超过5000个服务器，但是当我打开套接字连接时，几乎所有连接，检索错误操作现在正在进行中。

下面是我的客户端套接字连接代码:我怎么能同时做一个很好的数千套接字连接?对不起，我的英语不好。下面是我的代码:

struct sockaddr_in echoserver;
struct sockaddr_in sa_loc;
char aport[64];
int optval = 1;
int sock;
memset(&echoserver, 0, sizeof (echoserver));
echoserver.sin_family = AF_INET;  
echoserver.sin_addr.s_addr = inet_addr(server.c_str()); 
echoserver.sin_port = htons(0);     
SOCKET = socket(AF_INET, SOCK_STREAM, 0);
if (SOCKET == -1)
{
 iLastError = errno;
 strLastError = "Create socket Error : "+string(strerror(errno)); 
 connected = false;
 return connected;
}
struct timeval timeouts, timeoutr;
memset(&timeouts, 0, sizeof(timeouts)); // zero timeout struct before use
timeouts.tv_sec = SendTimeOut/1000;
timeouts.tv_usec = 0;
memset(&timeoutr, 0, sizeof(timeoutr)); // zero timeout struct before use
timeoutr.tv_sec = ReceiveTimeOut/1000;
timeoutr.tv_usec = 0;   
int sockopt = setsockopt(SOCKET, SOL_SOCKET, SO_SNDTIMEO, &timeouts, sizeof(timeouts)); 
if (sockopt == -1) 
{
 printf("%s%s","Set socket Option error : ",strerror(errno));
 iLastError = errno;
 strLastError = "setsockopt Error : "+string(strerror(errno));
}
sockopt = setsockopt(SOCKET, SOL_SOCKET, SO_RCVTIMEO, &timeoutr, sizeof(timeoutr)); // 
if (sockopt == -1) 
{
   printf("%s%s","Set socket Option error : ",strerror(errno));
   iLastError = errno;
   strLastError = "setsockopt Error : "+string(strerror(errno));
}
memset(&sa_loc, 0, sizeof(struct sockaddr_in));
sa_loc.sin_family = AF_INET;
sa_loc.sin_port = htons(0);  //8000
sa_loc.sin_addr.s_addr = inet_addr(SourceIP.c_str());
int bindid = bind(SOCKET, (struct sockaddr *)&sa_loc, sizeof(sa_loc));
if (bindid !=0) 
{
 iLastError = errno;
 strLastError = "Bind Error : "+string(strerror(errno));    
}
int conn = connect(SOCKET, (struct sockaddr *) &echoserver, sizeof(echoserver));
if (conn == -1)
{
 strLastError = "Connect Error : "+string(strerror(errno));   
 connected = false;
}
else {
 connected = true;
}
return connected;
