解决too many files

every socket is represented by a file descriptor

optimization:

• goroutines

在goroutines部分，采用epoll的方式

fd, err := unix.EpollCreatel(0)
if err != nil {
    return nil, err
}
fd := websocketFD(conn)
err := unix.EpollCtl(e.fd, syscall.EPOLL_CTL_ADD, fd, &unix.EpollEvent{}..)
if err !=nil {
    return err
}

reduce 30%

• buffers allocations
