oh-my-posh: Extreme slowness in Powershell Core Win10 Pro 19042.685

Prerequisites

Description

I loved oh-my-posh but slowness in GitRepos had me turn it off last year (v2). Its a new year so I decided to try v3 but it is extremely slow even with almost everything turned off. Its so slow that I think something must be wrong or setup wrong.

It takes 6231 ms for profile to load and takes 3 - 5 seconds to render a new line if I just press [ENTER].

What could be causing this and is there any way to debug?

Environment

Oh my Posh version: 3.68.2
Theme:
Operating System: Win10 Pro 19042.685
Shell: Powershell Core 7.1.0
Terminal: Windows Terminal but I’ve also tried it on a straight Pwsh window.

Steps to Reproduce

upgrade to omp v3
install CaskaydiaCove NF font in Windows Terminal
add omp v3 to pwsh profile
open a terminal window

Expected behavior: [What you expected to happen] prompts render and normal speed

Actual behavior: [What actually happened] prompts render very slowly 3 to 5 seconds and profile takes over 6000 ms to load.

          }
        }
      ]
    }
  ],
  "final_space": true
}

this is my profile script: C:\Users\ME\OneDrive - LBA Ware\Documents\PowerShell\Microsoft.PowerShell_profile.ps1

Invoke-Expression (oh-my-posh --init --shell pwsh --config ~/.poshthemes/jandedobbeleer-zack.omp.json);

function Get-PublicIp4 {
	Write-Host (invoke-webrequest "https://api.ipify.org?format=json").Content;
}

function Get-PublicIp6 {
	Write-Host (invoke-webrequest "https://api6.ipify.org?format=json").Content;
}

function ll {
	Get-ChildItem -Force $args;
}

#Clear-Host;

screenshot. this is me loading new shell and just pressing enter a few times while waiting for profile to load. you can see how long it takes to render each line after profile loads.

Now it looks amazing 115ms, I’m happy going to use oh-my-posh v3, thank you for your time ⌚🙏 @JanDeDobbeleer

@silverqx actually I think you helped identify an issue more users are experiencing (we were also never able to reproduce this). If you happen to have a git.cmd in your PATH that takes precedence over git.exe, you’re in for a ride.

JanDeDobbeleer on Mar 7, 2021

@silverqx I found the issue. You have a git.cmd file inside the bin folder. That one’s interpreted as an executable which is why the output doesn’t work anymore. When running git directly it works, but from go we’re stuck at that would-be executable. You can validate this by renaming that file.

I’m sure that 3.106.4 is loaded, I checked it by Get-Command -CommandType Function -Module oh-my-posh command, which also displays version numbers, just for the record. 🙂

silverqx on Mar 7, 2021

@silverqx chances are my latest release resolves this. We now no longer update the index which could’ve been the issue due to it being locked. That also explains why it happens for some people but not all.

JanDeDobbeleer on Mar 7, 2021

thank you for the clarification, I’m going to try to clone the problematic repo, …

Ok I have tried clone my repo and I can not reproduce the problem on a freshly cloned repo 🤔, so I compressed it and attached it here: dotfiles.zip

I absolutely don’t know what can cause this issue, I also tried to call git gc it didn’t help. @JanDeDobbeleer

silverqx on Mar 6, 2021

@silverqx unfortunately, that’s more related to git than oh-my-posh. There is some offset between running directly in the shell vs running it from go, but not seconds. We could omit status as that one’s taking up the time, but then again, you don’t want that everywhere. If someone can point me to an OSS git repo that has this issue, I’ll gladly see if we can speed things up a bit, but we already did a lot of work in that regard. Also, on Windows everything is noticeably slower compared to mac and linux. Not necessarily related to go either (we went fully crazy trying to validate the root cause end of last year).

I’ll check this again today
