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

測試用例二:啟用Buffer,連續插入20W行
1.Log4net
配置 log4net.config
......

<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"

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。
