Compress-Archive throws "OutOfMemory" on large folders

When using Compress-Archive on a very large folder, I am getting a "OutOfMemory Exception" error. This also happens when I pipe the folder from Get-ChildItem.

PS E:\> Compress-Archive -Path \\servername\downloads\foldername -DestinationPath e:\Foldername_bef -CompressionLevel Optimal
Exception calling "Write" with "3" argument(s): "Exception of type 'System.OutOfMemoryException' was thrown."
+ ... $destStream.Write($buffer, 0, $numberOfBytesRead)

    But setting Max memory seems a bit unnecessary and people are reporting mixed results.Compress-Archive should have some sort of memory management built-in like other programs like 7Zip. But presently Compress-Archive crashes after consuming all the System Memory.

    So... after a GREAT DEAL of research I ran across the solution. Microsoft PS remote sessions are memory limited to (I think, I didn't check the original value before setting to the new value) 150MB. My compression process usually (when run locally) took about 3GB.

    This StackOverflow post had the solution:

    They set to 1000 GB... tad excessive... I limited mine to 4GB:

    Set-Item WSMan:\localhost\Shell\MaxMemoryPerShellMB 4000
    Set-Item WSMan:\localhost\Plugin\Microsoft.PowerShell\Quotas\MaxMemoryPerShellMB 4000
    Restart-Service WinRM

    Ran into this exact issue when trying to encompass the Compress-Archive in an Invoke-Command to execute on a remote system. Command operates properly on remote system when executed on the system itself in a PowerShell console.
