Did you disable Antivirus or completely uninstalled? I'm asking
because from my experience many antiviruses are still hooked in
network stack even disabled. Only full uninstall helps.
Also I recommend using '--quiet' for tests because even redirecting to
$null can be slow in PowerShell.
Also issue can be caused by different disk flush polices on Windows
and Linux: could you try temporary turn off Windows write-cache buffer
flushing on the device:

I do not recommend this as solution, just to find root cause.
