az account show performance

[danijam]

Describe the bug
I spend most of my time using Azure through the CLI and have many different subscriptions. To help give me persistent visual context of which subscription I am currently operating against I make use of the PowerShell module oh-my-posh to display in my prompt the current Azure subscription name context. To show this oh-my-posh runs the command az account show this command is slow and therefore slows down my overall CLI experience as oh-my-posh has to wait for az account show to complete before it can render the prompt.

To Reproduce
Run at a PowerShell prompt measure-command { az account show }

Expected behavior
I'd expect this to be under <50ms but is actually over 500ms

Environment summary
Using az cli v2.30.0

Additional context
I have about 43 subscriptions available under az account list

I think you are using this? https://ohmyposh.dev/docs/az

We have already boosted Azure CLI performance from around 3000ms to 500ms via different methods:

• {Core} Build and use command index #13294
• {Core} Delay import #13843
• {Package} Migrate CLI packaging system to PEP 420 Implicit Namespace Packages #14372

az account show now takes around 500ms:

> Measure-Command { az account show }

TotalMilliseconds : 507.024

This is really the best we can get. Perhaps Oh My Posh can directly read from ~/.azure/azureProfile.json to get better performance? Even though directly reading this file is not supported, we haven't changed its schema for many years.
