.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
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
链接log4net 2.0.8
链接nlog 5.0.0-beta10
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。

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。
