使用JMSAppender发送2000条消息log4j2

Question

我正在尝试使用JMSAppender log4j2向ActivMQ发送日志。

我做了以下的conf

<?xml version="1.0" encoding="UTF-8"?> 
<Configuration monitorInterval="5"> 
    <Appenders> 
     <Console name="STDOUT" target="SYSTEM_OUT"> 
      <PatternLayout 
       pattern="%d{HH:mm:ss.SSS} %highlight{[%-5p] %c{1.} - %m} %style{(%t)}{Cyan}%n" /> 
     </Console> 
     <RollingFile name="fish" fileName="E:/fish/log/fish.server/fish.log" 
      filePattern="/log/fish.server/fish-%-d{yyyy-MM-dd-HH}.log"> 
      <PatternLayout pattern="%-d{yyyy-MM-dd HH:mm:ss.SSS} %5p %c{1} - %m%n" /> 
      <Policies> 
       <TimeBasedTriggeringPolicy /> 
      </Policies> 
     </RollingFile> 

     <JMS name="jmsQueue" destinationBindingName="logQueue" 
      factoryName="org.apache.activemq.jndi.ActiveMQInitialContextFactory" 
      factoryBindingName="ConnectionFactory" providerURL="tcp://xxxxxx:61616"> 
      <PatternLayout pattern="%-d{yyyy-MM-dd HH:mm:ss.SSS} %5p %c{1} - %m%n" /> 
     </JMS> 

    </Appenders> 
    <Loggers> 

     <Logger name="jmsLogger" level="warn"> 
      <AppenderRef ref="jmsQueue" /> 
     </Logger> 

     <Root level="warn"> 
      <!-- <AppenderRef ref="STDOUT" /> --> 
      <AppenderRef ref="fish" /> 
     </Root> 
    </Loggers> 
</Configuration> 

在那之后，我有32个线程streamExecutor其中做了一些工作人员，然后使用jmsLogger.warn（XXXX）的。

我曾经做过一个线程转储我的应用程序，我注意到以下阻断工作人员：？

所以现在的问题是，为什么在发送模式时线org.apache.activemq.ActiveMQConnection.syncSendPacket 。这造成了一些阻塞问题，并降低了我的表现。

Thnks很多:)

由于Log4j的2.7的，我不知道有任何性能基准测试使用JMS的appender记录。大部分已发布的基准测试都是针对文件日志。即使在多线程应用程序中，Log4j2也可以同步记录800K msg/sec到一个文件，持续，。异步日志可以快多倍地处理突发事件。

相比之下，2000 msg/sec似乎不是一个非常高的数字。我猜这取决于JMS实现库的吞吐量。
