提高ZeroMQ REQ/REP性能

我正在使用ZeroMQ 3.2.3和CZmq 1.4.1。我嘗試了「Hello world」示例。該示例（https://github.com/imatix/zguide/tree/master/examples/C）在使用10個併發客戶端時，允許我在本地主機（Ubuntu 13.04）上的Intel i7（8 GB RAM，共8個內核）上每秒最多交換12500條消息。提高ZeroMQ REQ/REP性能

我讀了ZeroMQ可以處理更多。我做錯了什麼，或者錯過了什麼？

下面是示例代碼：

// Hello World server 

#include <zmq.h> 
#include <stdio.h> 
#include <unistd.h> 
#include <string.h> 
#include <assert.h> 

int main (void) 
{ 
    // Socket to talk to clients 
    void *context = zmq_ctx_new(); 
    void *responder = zmq_socket (context, ZMQ_REP); 
    int rc = zmq_bind (responder, "tcp://*:5555"); 
    assert (rc == 0); 

    while (1) { 
     char buffer [10]; 
     zmq_recv (responder, buffer, 10, 0); 
     //printf ("Received Hello\n"); 
     zmq_send (responder, "World", 5, 0); 
     //usleep (1);   // Do some 'work' 
    } 
    return 0; 
} 



// Hello World client 
#include <zmq.h> 
#include <string.h> 
#include <stdio.h> 
#include <unistd.h> 

int main (void) 
{ 
    printf ("Connecting to hello world server...\n"); 
    void *context = zmq_ctx_new(); 
    void *requester = zmq_socket (context, ZMQ_REQ); 
    zmq_connect (requester, "tcp://localhost:5555"); 

    int request_nbr; 
    for (request_nbr = 0; request_nbr != 100000; request_nbr++) { 
     char buffer [10]; 
//  printf ("Sending Hello %d...\n", request_nbr); 
     zmq_send (requester, "Hello", 5, 0); 
     zmq_recv (requester, buffer, 10, 0); 
//  printf ("Received World %d\n", request_nbr); 
    } 
    zmq_close (requester); 
    zmq_ctx_destroy (context); 
    return 0; 
}

謝謝！
