The client is experiencing slow performance when copying many files from a Windows 11 machine to his NetApp storage array.
We used the same dataset (154 files / 15 MB).
- From a Windows 10 machine, the copy takes 20 to 30 seconds.
- From a Windows 11 machine, the copy takes 3 to 5 minutes.
- Same result from a clean Windows 11 installation.
- However, copying a large file (650 MB) shows no difference between Windows 10 and Windows 11 (around 20 to 40 seconds).
Many things have been tried by my endpoint consultant on Windows 11 machine without success, so we suspect network port configuration attached to the NetApp Storage Array and/or maybe NetApp configuration.
