Extremely high memory usage

Steps to reproduce

Run pwsh.exe

Expected behavior

The shell should open quickly and use very little memory.

Actual behavior

The shell opens, doesn't get to the prompt very quickly, then once running each pwsh.exe process uses rougly 250Mb of RAM (!!!)
For daily use this is not acceptable when compared to my typical shell workflow.

I’d reckon high memory usage for a shell that’s sitting idle to be a very specific and trackable issue. I’d love to see this situation improve.

As cool as it may be, it’s not worth the price of entry as a daily use shell. If you’re honestly cool with your idle terminals consuming over a Gb of RAM then more Power to you.

Ok I’ve tracked down the major consumer of RAM which was the AWS tools for PsCore.

If it uses Web cmdlets from PowerShell Core it is known issue and we have a tracking issue(s) for them (web cmdlets consume a lot of memory)
