详解.Net core2.0日志组件Log4net、Nlog简单性能测试
.net core之log4net、nlog简单性能测试
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。
测试环境
开发工具: vsual studio 2017 15.3
框架版本: .net core 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
测试用例
1.不启用buffer,连续插入20万行字符串到文件,单文件最大1mb。
2.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>

log4net耗时:

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>

nlog耗时:

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。
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。
