Frequent Lag and TCP RST Responses with NFS Server on WSL2 Debian 12

[shangwei2016]

Windows Version

10.0.22631.4317

WSL Version

2.3.24.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

5.15.153.1-2

Distro Version

Debian 12

Other Software

The NFS client is running on ARMv7-A development boards with a kernel version of 4.19. One board is from Rockchip, and the other is from MediaTek, both exhibiting the same behavior. Therefore, I believe it would be a good idea to first try using a Linux NFS client.

Repro Steps

1. Install NFS Server on WSL2, Debian 12
   1.1 sudo apt install nfs-common nfs-kernel-server rpcbind
   1.2 sudo mkdir /nfs
   1.3 sudo chown nobody:nogroup /nfs
   1.4 sudo chmod 777 /nfs
   1.5 Append '/mnt/nfs *(rw,sync,no_root_squash,no_subtree_check)' to /etc/exports
   1.6 sudo /etc/init.d/nfs-kernel-server restart
   1.7 sudo service rpcbind start

2. Execute commands on my development board
   2.1 mount -t nfs -o nolock 192.168.7.21:/nfs /nfsroot
   2.2 cd /nfsroot, if I operate files in this directory, such as the ls command, there is often a 3-second delay.

Expected Behavior

I expect file operations in the mounted directory to run smoothly and seamlessly, without frequent freezes or delays.

Actual Behavior

If I operate files in this mounted directory, such as the ls command, there is often a 3-second delay.
