            output.WriteLine($"NLog测试 total: {total}, Elapsed:{sw.ElapsedMilliseconds}");
        }

    }
}

测试用例一:不启用缓存,连续插入20W行

1.Log4net

配置

log4net.config


<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <!-- This section contains the log4net configuration settings -->
  <log4net>
    
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="logfile/" />
      <appendToFile value="true" />
      <rollingStyle value="Composite" />
      <staticLogFileName value="false" />
      <datePattern value="yyyyMMdd'.log'" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="1MB" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date | %message%newline" />
      </layout>
    </appender>

    <!-- Setup the root category, add the appenders and set the default level -->
    <root>
      <level value="ALL" />
      <appender-ref ref="RollingLogFileAppender" />
    </root>

  </log4net>
</configuration>

测试结果

输出日志内容:

2017-09-11 19:38:02,276 | log4 bigdata test: 0

2017-09-11 19:38:02,279 | log4 bigdata test: 1

... ...

2017-09-11 19:38:02,279 | log4 bigdata test: 199998

2017-09-11 19:38:02,279 | log4 bigdata test: 199999

Log4net耗时:

写入行数:200000, 毫秒数:7749

2.Nlog

配置

nlog.config


<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      autoReload="true"
      internalLogLevel="Warn"
      internalLogFile="internal-nlog.txt">

  <!-- define various log targets -->
  <targets>
    <!-- write logs to file -->
    <target xsi:type="File" name="ownFile-web" fileName="logs/nlog-own-${shortdate}.log"
              layout="${longdate} | ${message}" 
            archiveAboveSize="1048576"/>
  </targets>

  <rules>
    <logger name="*" minlevel="Trace" writeTo="ownFile-web" />
  </rules>
</nlog>

测试结果

输出日志内容:

2017-09-11 19:38:02,276 | nlog bigdata test: 0

2017-09-11 19:38:02,279 | nlog bigdata test: 1

......

......

2017-09-11 19:38:02,279 | nlog bigdata test: 199998

2017-09-11 19:38:02,279 | nlog bigdata test: 199999

Nlog耗时:

写入行数:200000, 毫秒数:104468

测试用例二:启用Buffer,连续插入20W行

1.Log4net

配置 log4net.config


......

  <log4net>
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <bufferSize value="100" />

......

耗时:

Log4net写入行数:200000, 毫秒数:4672

2.Nlog

配置

nlog.config


......

  <targets>
    <!-- write logs to file -->
    <default-wrapper xsi:type="BufferingWrapper" bufferSize="100"/>
    <target xsi:type="File" name="ownFile-web" fileName="logs/nlog-own-${shortdate}.log"
              layout="${longdate} | ${message}" 
            archiveAboveSize="1048576"/>
  </targets>

......

Nlog耗时:

写入行数:200000, 毫秒数:1605

总结

日志组件 版本 环境 用例 (启用Buffer=100)毫秒数 (不启用Buffer)毫秒数
log4net 2.0.8 .netcore 2.0 20W行文件写入 4672 7749
nlog 5.0.0-beta10 .netcore 2.0 20W行文件写入 1605 104468

代码和配置文件都在上边了,不知道不同配置的机器结果如何。

大家又会倾向于nlog还是log4net? log4net无论是否启用buffer,耗时都比较稳定,10秒以内,前后差距1.66倍;nlog在启用buffer前后,耗时差距65倍 ,未启用buffer竟然需要100多秒,虽然在启用buffer后仅1.605秒。
