发现一个奇怪的问题
背景是这样的：有多个client发送数据，server负责接收，然后写入数据库。为了提高效率，我把数据拼接到一起再写入数据库。测试的拼接是这样写的，其中$data最后以“\n”结束，我没有去掉它，所以是一行一行的： {{{ public function onReceive( swoole_server $serv, $fd, $from_id, $data ) { $this->sql = $this->sql . '|' .$data; } }}} 然后使用定时器定时输出 $this->sql 结果输出后，发现会出一个奇怪的状况：正常情况应该是每一行数据前面都会有“|”，但是输出的结果是这样的： {{{ 3, 0.26,0.46,0.20,68,0.00 |3, 0.62,0.34,-0.28,69,0.00 |3, 0.53,0.50,-0.03,70,0.00 3, 0.07,0.21,0.14,71,0.00 |3, 0.41,0.02,-0.39,72,0.00 |3, 0.24,0.11,-0.13,73,0.00 3, 0.72,0.57,-0.14,74,0.00 |3, 0.04,0.03,-0.02,75,0.00 |3, 0.08,0.08,0.00,76,0.00 3, 0.72,0.03,-0.69,77,0.00 |3, 0.67,0.14,-0.53,78,0.00 |3, 0.68,0.09,-0.59,79,0.00 3, 0.80,0.33,-0.47,80,0.00 }}} 请问这该如何解决呢？

因为TCP通信是流式的，在接收1个大数据包时，可能会被拆分成多个数据包发送。多次Send底层也可能会合并成一次进行发送。 http://rango.swoole.com/archives/464

貓朵朵。
谢谢您的回答，事实上我注意到了这个问题，也配置了参数： {{{ $this->serv->set(array( 'worker_num' => 8, 'daemonize' => false, 'max_request' => 10000, 'dispatch_mode' => 2, 'debug_mode'=> 1 ,
