<h1 style="color: black; text-align: left; margin-bottom: 10px;">测试</h1>
准备50条线程同期记录1000000条数据，而后统计时间，仔细代码如下：import
java.util.concurrent.CountDownLatch;import
 org.slf4j.Logger;import
 org.slf4j.LoggerFactory;public class App 
{    private static
 Logger log = LoggerFactory.getLogger(App.class);    public static void main(String[] args) throws InterruptedException 
{        int messageSize = 1000000
;        int threadSize = 50
;        final int
 everySize = messageSize / threadSize;        finalCountDownLatch cdl =new
 CountDownLatch(threadSize);        long
 startTime = System.currentTimeMillis();        for (int ts = 0
; ts < threadSize; ts++) {            new Thread(new
 Runnable() {                @Override                public void run() 
{                    for (int es = 0
; es < everySize; es++) {                        log.info("======info"
);
                    }
                    cdl.countDown();
                }
            }).start();
        }
        cdl.await();        long
endTime = System.currentTimeMillis();        System.out.println("log4j1:messageSize = "
 + messageSize                + ",threadSize = " + threadSize + ",costTime = "                + (endTime - startTime) + "ms"
);
    }
}
log4j1和logback的同步和异步分别修改为对应的appender就行了
log4j2的异步方式供给了2中模式：
1.全局开启
设置Log4jContextSelector系统属性为：org.apache.logging.log4j.core.async.AsyncLoggerContextSelectorSystem.setProperty("Log4jContextSelector", "org.apache.logging.log4j.core.async.AsyncLoggerContextSelector"
);
2.混合同步异步模式不需要设置Log4jContextSelector，然则需要运用AsyncLogger标签
更加多仔细参考官方文档：http://logging.apache.org/log4j/2.x/manual/async.html#AllAsync
<h1 style="color: black; text-align: left; margin-bottom: 10px;">结果</h1>
分别测试完以后统计成表格如下：<img src="https://mmbiz.qpic.cn/mmbiz_png/JdLkEI9sZfe39A5picdNfpqh5RI8Hlk8TqNnNicqEKLC77LsIZ33BibepJ8p1ynRbWR9jicMic78mM8N5QOsD4EXQ4A/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">imglog4j2的异步模式表现了绝对的性能优良，优良重点得益于Disruptor框架的运用LMAX Disruptor technology. Asynchronous Loggers internallyuse the Disruptor, a lock-free inter-thread communication library, instead of queues, resulting inhigher throughputand lower
 latency.
一个无锁的线程间通信库代替了原来的队列
更加多Disruptor ：
