Steps to reproduce
If I'm doing "dir" on a network mapped drive the output is extremly slow, I can read line by line.
Output to screen:
u is a network drive
$start=(Get-Date)
dir u:\ # lists 580 entries
$end=(Get-Date)
$end-$start
Output to null:
u is a network drive
$start=(Get-Date)
dir u:\ | out-null # lists 580 entries
$end=(Get-Date)
$end-$start
Expected behavior
Roughly the same time (1 second)Actual behavior

doing a "dir" on a network drive takes 28 seconds to list a network drive
With CMD it's instant (same as output to null in Powershell)
The problem is independant if I use PS7 directly or via Terminal, so it's not the screenput itself that is slowing it.Environment data
