測試用例一:不啓用緩存,連續插入20W行

1.Log4net

配置

log4net.config單元測試

<?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>

Log4net耗時:

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>

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

Nlog耗時:

寫入行數:200000, 毫秒數:104468

測試用例二:啓用Buffer,連續插入20W行

1.Log4net

配置 log4net.config

......

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

......

耗時:

Log4net寫入行數:200000, 毫秒數: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耗時:

寫入行數:200000, 毫秒數:1605

總結

日誌組件 版本 環境 用例 (啓用Buffer=100)毫秒數 (不啓用Buffer)毫秒數
log4net 2.0.8 .netcore 2.0 20W行文件寫入 4672 7749
nlog 5.0.0-beta10 .netcore 2.0 20W行文件寫入 1605 104468

代碼和配置文件都在上邊了,不知道不一樣配置的機器結果如何。

你們又會傾向於nlog仍是log4net? log4net不管是否啓用buffer,耗時都比較穩定,10秒之內,先後差距1.66倍;nlog在啓用buffer先後,耗時差距65倍 ,未啓用buffer居然須要100多秒,雖然在啓用buffer後僅1.605秒。
