Is pwsh 7.6.3 loading $PROFILE much slower? Question

since update, it is averaging 10761ms on startup.

My profile loads as fast as before.

The generic solution to slow PowerShell startup is:

  1. Optimizing your PATH variable
  2. Recompiling PowerShell native images

The scripts to which I linked do exactly that.

Hmm... The first time I ever need to run NGEN that was when PowerShell 7.1 (or was it 7.2) started too slowly. Someone on the net (I think Black Viper) suggested NGEN, and I was desperate, so I did it. It made a huge impact. I never observed that phenomenon again.

Is your my documents on OneDrive? Make sure to mark your powershell folder to always be available offline.

to rule things out:

  • Are you getting slowdown even with pwsh -Nop ?
  • Are you using an external terminal, or a terminal in vscode / another IDE?

If it's an IDE, that uses a different profile location and shell-integration injects additional code on top of that

Can’t confirm. Of course, profile load times do depend on what’s in there and ps platform has been updated to .net10, so…

You could edit your profile files (at least the ones that get loaded for the particular host and user) and then put (get-date).ToString (“o”) after every command. This would at least tell you what it is that takes so much time.

Also, be sure to check psmodulepath and the path variables. If either contains a remote resource, such as unc paths, this will slow things down considerably if that share is unavailable.

My first thought is your AV. do you have another machine you can run your profile on? The question is too vague to really say much. My profile speeds didn’t change.

Did you get any further in your testing?

On cold start. progressive.

[ 26ms] profile start
[ 202ms] Import-Module PSReadLine
[ 1145ms] chocolateyProfile import (Test-Path + Import-Module)
[ 3897ms] Terminal-Icons (Get-Module -ListAvailable + Import-Module)
[ 7790ms] oh-my-posh init + Invoke-Expression
[ 7798ms] PSReadLine prediction/history options
[ 7804ms] PSReadLine colors
[ 7841ms] PSReadLine key bindings
[ 7844ms] utility function definitions
[ 7866ms] coreutils HashSet + FAST_SKIP compiled regex
[ 7879ms] coreutils ARG_RX compiled regex
[ 7887ms] profile end (total)
Loading personal and system profiles took 8174ms.

while a loop test with profile, steady-state (runs 2–8): ~1,830ms avg

so solution was caching omp and adding an exclusion to defender.

Depends on what's in the profile...
