套接字接受在Windows上消耗我的内存而不释放

问题是,每个连接都会占用一些内存,而不会在任何时候将其释放到操作系统.我用大约300K请求运行ab(apache基准测试),并且进程内存不断增长(最后几百兆字节).

我知道进程并不总是将其空闲内存返回给操作系统.但是一旦它超过几兆字节,我认为它应该返回内存还是我错了？

这只发生在Windows上.在Linux上,我的内存使用率几乎都是进程启动使用的.

用GCC 4.8.2编译.在Windows Server 2008 R2和Windows 8.1上测试过.

void http_server_start(void) {
  int rc;
  struct sockaddr_in cfg;

  #ifdef _WIN32
  WORD ver;
  WSADATA data;
  ver=MAKEWORD(2,2);
  rc=WSAStartup(ver,&data);
  if(rc != 0){
    printf("Error: Unable to initialize WSA (%d)",rc);
  }
  #endif

  memset(&cfg,sizeof(cfg));
  cfg.sin_family = AF_INET;
  cfg.sin_addr.s_addr = htonl(INADDR_ANY);
  cfg.sin_port = htons(PORT);
  server = socket(AF_INET,SOCK_STREAM,6);
  int reuseaddr=1;
  if (setsockopt(server,SOL_SOCKET,SO_REUSEADDR,(char*)&reuseaddr,sizeof(reuseaddr)) == -1){
    rc=GetLastErrorEx();
    printf("Error: Unable to set SO_REUSEADDR (%d)\n",rc);
  } else if (bind(server,(struct sockaddr *)&cfg,sizeof(cfg)) < 0 ) {
    rc=GetLastErrorEx();
    printf("Error: Unable to bind socket (%d)\n",rc);
    close(server);
  } else if (listen(server,QUEUE_SIZE) < 0) {
    rc=GetLastErrorEx();
    printf("Error: Unable to listen (%d)\n",rc);
    close(server);
  } else {
    printf("Listening on %s:%d\n",inet_ntoa(cfg.sin_addr),ntohs(cfg.sin_port));
    int client;
    struct sockaddr_in addr;
    int addrlen=sizeof(addr);
    do {
      client=accept(server,(struct sockaddr*)&addr,&addrlen);
      if(client != -1){
        shutdown(client,SHUT_RDWR);
        close(client);
      }
    } while(1);
  }
}
