PowerCli load time is insane

[MichaelRyom]

Hi

What is up with the extreme load time of the recent version of PowerCli. This is getting out of hand 😞 It takes now more than 4 min to load PowerCli on my laptop! Compared to v11 it was only around 1min to load all the modules. I see this across servers (VMs) and different laptops and OS's ( Windows Server 2019/Client 10/11). I anyone else seeing this or having a fix for it?

PS C:\Users\Michael Ryom> Get-Module vmware.powercli -ListAvailable | Select Name,Version

Name            Version
----            -------

On a server I tried to load the module one at a time and a few takes a lot of time

Is there anyway to disable module that are not needed, to speed things up?

I think that I asked you in another of your threads why you do an

Import-Module -Name VMware.PowerCLI

in a script.

If your PowerCLI modules are in a folder listed in $env:PSModulePath there is absolutely no need for that.
The PS engine will load the required module the first time you use a cmdlet from that module.

Also note that since PowerCLI 12.4 (or 12.5) there have been a lot of new modules added, all starting with 'VMware.Sdk.vSphere.'.
And which you probably aren't using.
Those added modules explain part of the additional load time when you do that Import-Module -Name VMware.PowerCLI in a script.

The only reason why I might load a module explicitly is when my script uses a Type that is defined in that module (before it uses a cmdlet from that module).
Unfortunately, the PS engine does not automatically load modules on use of a Type.
