開發工具: Vsual Studio 2017 15.3 框架版本: .net core 2.0 操做系統:window10 Enterprise 1703 硬件配置:CPU I3-4170 3.7GHz,內存 8G,固態硬盤
連接log4net 2.0.8緩存
連接nlog 5.0.0-beta10app
不啓用Buffer,連續插入20萬行字符串到文件,單文件最大1MB。框架
啓用Buffer爲100,連續插入20萬行字符串到文件,單文件最大1MB。工具

代碼和配置文件都在上邊了,不知道不一樣配置的機器結果如何。
你們又會傾向於nlog仍是log4net? log4net不管是否啓用buffer,耗時都比較穩定,10秒之內,先後差距1.66倍;nlog在啓用buffer先後,耗時差距65倍 ,未啓用buffer居然須要100多秒,雖然在啓用buffer後僅1.605秒。
