Spring boot Spring boot log4j2 vs logback性能

在spring boot webapp中，我看到logback的性能优于log4j2。logback和log4j2 webapps非常简单。在调试级别记录消息的单个控制器。立面采用SLF4j。在这两种情况下，日志配置只有根记录器处于错误级别。测试由jmeter运行，HTTP多次访问运行log语句的控制器。结果表明，logback的性能比log4j2高出约36%。测试结果是一致的。测试在aws c5.2x大型实例上运行

我希望有人能把它放在自己的测试环境中，并验证结果。我本以为这对log4j2来说是一个相当重要的问题，但我还没有读到任何关于它的文章。据我所知，这两个webapp的日志实现路径相似

我将分享两个spring boot Web应用程序的主要部分
