windows-server-2012-r2 – 如何调整Windows Server 2012 R2以处

我有一个开发人员实用程序,我将用它来生成5000万个文件.目录结构深入四级.顶级包含16个目录(2000 – 2016年),下一级 – 月(1-12),下一级 – 天(1 – 31),最后是 – xml文件(每个最多85k).最终目录可能有3000个文件(我还没有完成数学计算,以确定5000万个文件是否适合该目录结构).

我目前正在运行该实用程序,我大约需要1/3(执行的天数).正如我所担心的那样,遍历目录树的任何部分都是一种痛苦的经历.在浏览器中需要几秒钟.这与服务器级硬件. SAS 7200RPM(我知道现在不是很快)12TB Raid 5或10,分配4个3.4ghz xeon cpus.

如何提高Windows Server 2012 R2在内存中缓存文件句柄的能力？我没有运行NFS服务.
