Issue Description

VSCode Version: 1.20.1
OS Version: Server 2016
PowerShell Extension 1.5.1
PowerShell Version 5.1

Steps to Reproduce:

Open a new document with PowerShell as language
Type in 'Get-' (or any other command) and wait 4-10 seconds for Intellisense to complete

Does this issue occur when all extensions are disabled?: No - Related to PowerShell Extension, HTML intellisense works great

System Info:
CPU: Intel (R) Xeon(R) CPU E5-2660 v3 @ 2.60GHz (4 x 2598)
Memory: 24.00GB (16.08GB free)
Process Argv: C:\Program Files\Microsoft VS Code\Code.exe
Screen Reader: no
VM: 100%

Notes:

It does not matter if I try any other command, or type in more of it so there's only one option for it.
PowerShell ISE intellisense is immediate
VSCode (same versions) on desktop works exactly how I'd expect it.
This was not introduced with a new version, been a problem since beginning.
I tried to use the issue reporter, the 'Preview On Github' button wasn't performing any actions.
It does not matter if it's the first time I try intellisense on a type of command.

Note: This is in the editor, not the terminal. Terminal intellisense works fine.

Can you attach a zip of the extension log files? See the following for instructions on how to do this - https://github.com/PowerShell/vscode-powershell#2-capture-verbose-logs-and-send-them-to-us

I updated to the PowerShell extension 1.6 and no change in behavior

Hmm everything is clipping along nicely until we attempt to process your profile:

Could you temporarily rename your profile file - C:\Users\su-rp53\Documents\WindowsPowerShell\profile.ps1? Stick a .bak on it or something and then retry VSCode to see if the perf issue still exists. If it doesn't, we'll need to figure out what's going on with your profile.

clavrus · 2018-02-23T14:32:18Z

You were correct. My profile.ps1 is set up to import a number of my commands, but I think I've identified the one line that vscode isn't liking.

Import-Module C:\scripts\modules\trconfig.psm1 - If I comment out this line, vscode intellisense is much snappier.

I've added the trconfig.txt for your reference. I don't see anything in it that should cause problems. I am able to import a different .psm1 file that has thousands of lines of functions without any problem.

Any ideas from looking at the trconfig on where to start before I start testing removing things from it?
trconfig.txt

clavrus · 2018-02-23T14:44:42Z

It looks like it's this line that's causing it.

I have quite bad slowness too. All I see is "waiting..." for 10-30s everytime I try to use insellisense. Logs attached. Tried to disable everything in profile, no change.

@veepee78 Thanks for attaching your log files! In your EditorServices.log file I'm seeing a 10 second gap every time we invoke PSSA (part of a codeLens/resolve request):

2018-02-23 10.50.22 [VERBOSE] - Method "ReadMessage" at line 123 of C:\projects\powershelleditorservices\src\PowerShellEditorServices.Protocol\MessageProtocol\MessageReader.cs

    Received Event '$/cancelRequest'

CodeLens/PSSA should be running in the background until you click on one. Also, the slowest IntelliSense response I've seen from the language server in the log file is:

2018-02-23 10.51.05 [VERBOSE] - Method "GetCompletions" at line 135 of C:\projects\powershelleditorservices\src\PowerShellEditorServices\Language\AstOperations.cs

    IntelliSense completed in 108ms.

That doesn't mean that there isn't something on the client-side (VSCode side) that is slow.

Going to deduplicate this issue to #647.
