This article mainly introduces. Net core2.0 log components Log4net, Nlog simple performance test example analysis, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

Test environment

Development tools: Vsual Studio 2017 15.3

Framework version: .net core 2.0

Operating system: window10 Enterprise 1703

Hardware configuration: CPU I3-4170 3.7GHz, 8G memory, solid state disk

Log component

Log4net 2.0.8

Nlog 5.0.0-beta10

Test case

1. Do not enable Buffer, insert 200000 lines of strings into the file continuously, and the maximum 1MB for a single file.

two。 Enable Buffer to be 100, insert 200000 lines of strings into the file continuously, and the maximum 1MB for a single file.

Testing method

Xunit unit test.

Test code

Using System;using System.Diagnostics;using System.IO;using Xunit;using Xunit.Abstractions;namespace Demo.Logging.Tests {/ Log4net, Nlog log file write comparison / public class BigDataTest {private readonly ITestOutputHelper output; public BigDataTest (ITestOutputHelper outputHelper) {output = outputHelper } / [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; iTunes +) {log.Info ("log4 bigdata test:" + I);} sw.Stop (); log.Info ($"total: {total}, Elapsed: {sw.ElapsedMilliseconds}") Output.WriteLine ($"Log4net Test total: {total}, Elapsed: {sw.ElapsedMilliseconds}"); / [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; iTunes +) {log.Info ("nlog bigdata test:" + I);} sw.Stop (); log.Info ($"total: {total}, Elapsed: {sw.ElapsedMilliseconds}"); output.WriteLine ($"NLog Test total: {total}, Elapsed: {sw.ElapsedMilliseconds}");}

Test case 1: do not enable caching, insert 20W rows continuously

1.Log4net

Configuration

Log4net.config

Test result

Output log contents:

2017-09-11 1914 385 02276 | log4 bigdata test: 0

2017-09-11 19 38 14 02279 | log4 bigdata test: 1

2017-09-11 19 38 14 02279 | log4 bigdata test: 199998

2017-09-11 19 38 14 02279 | log4 bigdata test: 199999

Log4net time consuming:

Lines written: 200000, milliseconds: 7749

2.Nlog

Configuration

Nlog.config

Test result

Output log contents:

2017-09-11 1914 385 02276 | nlog bigdata test: 0

2017-09-11 19 38 14 02279 | nlog bigdata test: 1

2017-09-11 19 38 14 02279 | nlog bigdata test: 199998

2017-09-11 19 38 14 02279 | nlog bigdata test: 199999

Nlog time consuming:

Lines written: 200000, milliseconds: 104468

Test case 2: enable Buffer and insert 20W rows continuously

1.Log4net

Configure log4net.config

. .

Time elapsed: rows written by Log4net: 200000, milliseconds: 4672

2.Nlog

Configuration

Nlog.config

. .

Nlog time: lines written: 200000, milliseconds: 1605

Summary

Log component version environment use case (enable Buffer=100) milliseconds (not Buffer enabled) milliseconds log4net2.0.8.netcore 2.020W line file write 46727749nlog5.0.0-beta10.netcore 2.020W line file write 1605104468

The code and configuration files are all above, and I don't know how the machines with different configurations will turn out.

Will people prefer nlog or log4net again? The time consumption of log4net is stable regardless of whether buffer is enabled or not. The time difference between before and after enabling buffer for nlog is 65 times, and it takes more than 100 seconds for buffer not to be enabled, although it is only 1.605 seconds after enabling buffer.

Thank you for reading this article carefully. I hope the article "sample Analysis of simple performance testing of .net core2.0 Log Module Log4net and Nlog" shared by the editor will be helpful to you. At the same time, I also hope that you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
