关于DWR性能的讨论

[lcj_up]

本人用台式机I5-4440+8G+TOMCAT7运行最简单的DWR推送代码如下：

	public static void sendMsg(String msg,String targetUserId) {
		Container container = ServerContextFactory.get().getContainer();  
		ScriptSessionManager manager = container.getBean(ScriptSessionManager.class); 
		Collection<ScriptSession> sessions = manager.getAllScriptSessions();
    	System.out.println(sessions.size());
        for (ScriptSession session : sessions) {
	            ScriptBuffer sb = new ScriptBuffer();
	            Calendar time  =Calendar.getInstance() ;
	            String s = time.get(Calendar.YEAR) + "-" + time.get(Calendar.MONTH) + "-" +  time.get(Calendar.DAY_OF_MONTH) + " " 
	                    +  time.get(Calendar.HOUR) + ":" +  time.get(Calendar.MINUTE) + ":" + time.get(Calendar.SECOND) ;
	
	            sb.appendScript("showMsg({msg: '")
	            .appendScript(msg)
	            .appendScript("', time: '")
	            .appendScript(s)
	            .appendScript("'})");
	            session.addScript(sb);
        }
	}

客户端代码

function sendMsg(){
	//$.post("msgMgt/showMsg.action",{'msg':$('#text_in').text()});
	DwrUtil.sendMsg($('#text_in').text()); 
};

function showMsg(data){
	displayMsg('<p>'+data.time+'<br/>'+data.msg+'</p>');
	$('#text_in').html('');
};

但是目前遇到这么一个问题、只要运行DWR页面数量超过5个 tomcat的响应就会特别慢...
有哪位大神有关于优化dwr和tomcat的建议请指导一下...

交流贴 分数少见谅

用jconsole监控了一下内存，没有发现任何异常...

DWR??还是JQUERY比较靠谱吧!
