看是否能优化

Why is this needed?

看文档CubeFS十分钟入门 | 基于FTP、NFS、SMB跨平台使用中可以对接NFS,在linux上试了一下,写性能太差,分析了一下原因是频繁Attr操作InodeGet造成的,看正常情况下不使用NFS,直接写cfs-client挂载点并不会产生InodeGet热点,具体NFS的问题还需要分析一下,热点分析对接的NFS-Ganesha, 性能测试NFS-Ganesha 和 nfs-util都测了.

Anything else?

cfs-client icacheTimeout 设置长一点可以缓解

@BillXiang Could you explain the specific test methods and data?

[BillXiang]

测试方法就是https://mp.weixin.qq.com/s/PyOwFzOSZK0pe6Xd0MnHJQ这篇文章里的,但是我没有用windows.还是在linux上挂载了nfs,fio顺序写大概只有6MB/s,cfs-client热点函数已经定位到InodeGet了 @leonrayang 您那边是复现不了还是不知道咋复现
