.Netcore之Log4net、Nlog性能比较

最近在写一个开源.netcore web框架，需要一个高性能的日志组件。目前要从log4net、nlog二选一，大家应该都有了解，就不赘述了。此文目的是比较log4net、nlog的文件写入性能（.netcore环境），涉及代码和配置如有不正确的地方，还请批评指正。楼主已经和日志杠上了。楼主是个喜欢写代码，不喜欢写文档的猿，多久才写一篇文，真懒额！切入正题

测试环境

开发工具： Vsual Studio 2017 15.3框架版本: .netcore 2.0操作系统：window10 Enterprise 1703硬件配置：CPU I3-4170 3.7GHz，内存 8G，固态硬盘

日志组件

链接log4net 2.0.8

链接nlog 5.0.0-beta10

测试用例

不启用Buffer，连续插入20万行字符串到文件，单文件最大1MB。
启用Buffer为100，连续插入20万行字符串到文件，单文件最大1MB。

测试方法

xunit单元测试。

测试代码

using System;using System.Diagnostics;using System.IO;using Xunit;using Xunit.Abstractions;namespace Demo.Logging.Tests{    /// <summary>    /// Log4net、Nlog日志文件写入对比    /// </summary>    public class BigDataTest    {        private readonly ITestOutputHelper output;        public BigDataTest(ITestOutputHelper outputHelper)        {            output = outputHelper;        }        /// <summary>        /// 使用Log4net连续插入20W行字符串        /// </summary>        [Fact]        public void Log4netTest()        {            log4net.Repository.ILoggerRepository repository = log4net.LogManager.CreateRepository("NETCoreRepository");            var fileInfo = new FileInfo("config/log4net.config");            log4net.Config.XmlConfigurator.Configure(repository, fileInfo);            log4net.Config.BasicConfigurator.Configure(repository);            log4net.ILog log = log4net.LogManager.GetLogger(repository.Name, "NETCorelog4net");            var total = 200000;            var sw = new Stopwatch();            sw.Start();            for (int i = 0; i < total; i++)            {                log.Info("log4 bigdata test: " + i);            }            sw.Stop();            log.Info($"total: {total}, Elapsed:{sw.ElapsedMilliseconds}");            output.WriteLine($"Log4net测试 total: {total}, Elapsed:{sw.ElapsedMilliseconds}");        }        /// <summary>        /// 使用Nlog连续插入20W行字符串        /// </summary>        [Fact]        public void NlogTest()        {            NLog.Logger log = NLog.LogManager.GetCurrentClassLogger();            var total = 200000;            var sw = new Stopwatch();            sw.Start();            for (int i = 0; i < total; i++)            {                log.Info("nlog bigdata test: " + i);            }            sw.Stop();            log.Info($"total: {total}, Elapsed:{sw.ElapsedMilliseconds}");            output.WriteLine($"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log4net2.0.8.netcore 2.020W行文件写入467217749 (更正)nlog5.0.0-beta10.netcore 2.020W行文件写入1605104468

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。
