定时器是否会影响收数据

$worker = new Worker('tcp://0.0.0.0:9090'); //http协议
//启动1个进程对外提供服务
$worker -> count = 1;
Worker::$daemonize = true;
Worker::$stdoutFile = '/tmp/stdout.log';
//增加一个属性
$worker -> uidConnections = array();
$worker -> onWorkerStart = function($worker){
   $worker -> onConnect = function($connection){
      global $worker;
      $ip = $connection -> getRemoteIp();
      $id = $connection -> id;
      $worker -> uidConnections = $connection;
      echo "连接成功";
           $GLOBALS = Timer::add(0.001,array('DealData','dealSream'),array($id, $connection),true);//隔1ms处理一次stream
   };
   $worker -> onMessage = function($connection,$datas){
      //#考虑校验
           $id = $connection -> id;
           if(!isset($GLOBALS)){
               $GLOBALS = $datas;
           }else{
               $GLOBALS .= $datas;//接收流到缓冲区
           }
   };

比如这段程序，
1.如果我的定时器那边还没执行完的情况下，onmessage区间是否还能正常接收存储数据？
2.如果我设置进程数是2或者更多，是系统自动选择进行执行，还是需要手动规定某个进程执行哪些业务,比如if（$worker -> id ==0）{第一个进程}else{其他进程业务}？
3.‘1’问题中定时器会影响收数据，那我能不能开两个进程，一个进程专门运行定时器处理数据，另一个进程做目前的其他业务。改成这样的代码

$worker = new Worker('tcp://0.0.0.0:9090'); //http协议
//启动1个进程对外提供服务
$worker -> count = 2;
Worker::$daemonize = true;
Worker::$stdoutFile = '/tmp/stdout.log';
//增加一个属性
$worker -> uidConnections = array();
$worker -> onWorkerStart = function($worker){if($worker -> id == 0){$GLOBALS = Timer::add(0.001,array('DealData','dealSream'),array($id, $connection),true);//隔1ms处理一次stream}else{
   $worker -> onConnect = function($connection){
      global $worker;
      $ip = $connection -> getRemoteIp();
      $id = $connection -> id;
      $worker -> uidConnections = $connection;
      echo "连接成功";

   };
   $worker -> onMessage = function($connection,$datas){
      //#考虑校验
           $id = $connection -> id;
           if(!isset($GLOBALS)){
               $GLOBALS = $datas;
           }else{
               $GLOBALS .= $datas;//接收流到缓冲区
           }
   };
