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服务器之家。
