.Netcore之Log4net、Nlog性能比較

最近在寫一個開源.netcore web框架,需要一個高性能的日誌組件。目前要從log4net、nlog二選一,大家應該都有了解,就不贅述了。

此文目的是比較log4net、nlog的文件寫入性能(.netcore環境),涉及代碼和配置如有不正確的地方,還請批評指正。樓主已經和日誌杠上了。樓主是個喜歡寫代碼,不喜歡寫文檔的猿,多久才寫一篇文,真懶額!

切入正題

測試環境

開發工具: Vsual Studio 2017 15.3

框架版本: .netcore 2.0

操作系統:window10 Enterprise 1703

硬件配置:CPU I3-4170 3.7GHz,內存 8G,固態硬盤

日誌組件

鏈接log4net 2.0.8

鏈接nlog 5.0.0-beta10

測試用例

  1. 不啟用Buffer,連續插入20萬行字符串到文件,單文件最大1MB。

  2. 啟用Buffer為100,連續插入20萬行字符串到文件,單文件最大1MB。

測試方法

xunit單元測試。

測試用例一:不啟用緩存,連續插入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">

<?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"

              layout="${longdate} | ${message}" 
            archiveAboveSize="1048576"/>

  </rules>
</nlog>

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: 199999

Nlog耗時:

寫入行數:200000, 毫秒數:104468

測試用例二:啟用Buffer,連續插入20W行

1.Log4net

配置 log4net.config


......

  <log4net>
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <bufferSize value=http://www.cnblogs.com/supernebula/p/"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 (啟用Buffer=100)毫秒數 (不啟用Buffer)毫秒數 log4net 2.0.8 .netcore 2.0 20W行文件寫入 4672 17749 (更正) 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,不知道不同配置的機器結果如何。
