proxmox更新到7版後
在管理介面 mount nfs 可以選 v3 或 v4
用fio測一下 v3 和 v4 的效能差別
config 如下
# This job file tries to mimic the Intel IOMeter File Server Access Pattern

# IOMeter defines the server loads as the following:
# iodepth=1 Linear
# iodepth=4 Very Light
# iodepth=8 Light
# iodepth=64 Moderate
# iodepth=256 Heavy
iodepth=64
測三次 取最後一次的值如下
