我正在进行 Apache camel 的性能测试，到目前为止，我能够运行 logback async 来获得一些速度，
在开始我的路线时，无论如何都要禁用驼峰上下文的 INFO 。
logback.xml：
我的logback.xml配置是，
<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false" scan="false">
<statusListener class="ch.qos.logback.core.status.NopStatusListener" />
<!-- To show the log in console -->
<appender name="OUT" class="ch.qos.logback.core.ConsoleAppender">
<prudent>true</prudent>
<encoder>
<Pattern>
%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
</Pattern>
</encoder>
</appender>
<logger name="org.apache.catalina.core" level="INFO" />
<!-- DEBUG Config -->
<logger name="logs_debug" level="DEBUG" additivity="false">
<appender-ref ref="OUT" />
</logger>
<!-- INFO Config -->
<logger name="logs_info" level="INFO" additivity="false">
<appender-ref ref="OUT" />
</logger>
<!-- ERROR Config -->
<logger name="logs_error" level="ERROR" additivity="false">
<appender-ref ref="OUT" />
</logger>
<!-- To make the Logback ASYNC -->
<appender name="ASYNC" class="ch.qos.logback.classic.AsyncAppender">
<includeCallerData>true</includeCallerData>
<queueSize>500</queueSize>
<discardingThreshold>2</discardingThreshold>
<appender-ref ref="OUT" />
</appender>
<!-- root Logback -->
<root level="ERROR">
<appender-ref ref="ASYNC" />
</root>
</configuration>
我得到了这个回复。

不，我不这么认为，因为你使用camel-maven-plugin启动Camel，这是一个Maven插件，它有自己的启动和日志记录，在Camel启动之前发生等等。
如果你想完全没有日志记录，那么自己启动Camel作为java主应用程序。
现在重点是你真的不应该浪费时间，因为启动是可以忽略的，不应该在你的性能测试中测量。只有当应用程序启动并运行时，您可能需要调整/调整日志/ JMX /线程等等以获得更高的性能。

尝试从骆驼网站查看link。
日志提供了一些选项： 要使用的记录级别。可能的值：ERROR，WARN，INFO，DEBUG，TRACE，OFF
可以像这样使用：
.log(LoggingLevel.ERROR, "some error to log")

我有log4j，配置如下，对我来说效果很好
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>
</head>
<body>
<input type="button" value="Sort" id="sort"></input>
<table cellpadding="1" cellspacing="1" id="mytable" border="1">

<script type="text/javascript" language="javascript">
$("#sort").click(function(){
$('#mytable tr').each(function() {
var arr=[];
var x = $(this).find("td").eq(1).text();
arr.push(x);
SortElements();
});
})
function SortElements() {
arr.sort(alphabetical);
alert(arr);
}
function alphabetical(a, b)
{
var A = a.toLowerCase();
var B = b.toLowerCase();
if (A < B){
return -1;
}else if (A > B){
return 1;
}else{
return 0;
}
}
</script>
</body>
</html>
我认为对于logback也会是这样的。
