适用场景

  • ONTAP 9
  • NFSv3到4.2

问题解答

  • 原因如下:
    • NFSv3不需要锁定
      • 锁定会增加NFS客户端和服务器的开销
      • 锁定还可能需要与其他客户端进行通信、从而进一步增加延迟
    • 在NFSv3中、每次调用都是一个单独的RPC调用
      • 根据工作负载的不同、速度可能更快或更慢
    • 委派等功能可将负载转移到其他客户端
      • 其他客户端需要处理委派会造成额外的延迟
    • NFSv4会保留可能无法高效执行的状态
    • 较旧版本的Linux或ONTAP 不如较新版本的优化效果更好、无法实现NFSv4.x的最佳性能
