use epoll single-threaded monitored data reception efficiency problem, 
Int epoll_fd; 
Int socktfd=socket (... ) 

Listen (sockfd,... ) 

Bind (sockfd,... ) 

Epoll_fd=epoll_create (MAX_EVENTS);//handle to create an epoll 

//
//the add server socket fd into epoll system 
//
Epoll_ctl (epoll_fd, EPOLL_CTL_ADD, server_sockfd,.. ) 

for( ; ;) {
//
//wait fd set data in or out 
//
NFDS=epoll_wait (epoll_fd, events, MAX_EVENTS, 1); 

For (int I=0; iIf (events [I]. Data. Fd==server_sockfd) {
///accpet one client 
//and add to epoll system 
AccpetAndAdEpollSys (); 
} 
The else {
///recv data from client 
The recv (... ); 
//
//handler client message data 
//
MessageHandler (... ); 
} 
} 
} 

Want to ask if the concurrency value is very big, recv received come over? Whether can use multithreading to receive? Or how to deal with?

CodePudding user response:

Or not so absolutely do multithreading, can restrain conditions, such as how many client a thread management, group management client,
