[Bug] Performance issue in pre 6.0.0-beta.1

[facusantillo]

Describe the bug
Moving pipeline from release 6.0.0-alpha.1 to 6.0.0-beta.1 with same definition files takes 5x times more to calculate the version

Expected Behavior

Calculate version in release 6.0.0-alpha.1 took around 2 minutes.

Actual Behavior

In version 6.0.0-beta.1 took approx 10 min

Context

This is a little bit tricky. In repos with 200+ tags with lots of PR's in the alpha version calculating the version is almost instant while the beta takes too long to finish. We are using the continuous delivery mode.

Your Environment

• Version Used: 6.0.0-beta.1
• Operating System and version: Azure DevOps, Self-Hosted Agent with Windows-2022 as vmImage
• Link to your project: it's private project from the organization
• Link to your CI build (if appropriate): it's private project from the organization

First I would like to thank you for reporting your experience with the pre release version 6.0.0-beta.1. I have seen some issues (like #3212) which are related to performance but they are pending. Please don't get my point wrong: But in my opinion it's not so pleasant to create a bug and say it's 10 times higher without providing any information about your environment. You know that we are working on this project in our spare time right!? It's a community work and you are part of it.

May I ask you to help us with the following one or more points:

• Give background information about your context/environment
• Find out where the problem might be located (Is it because of so many tags? Is it because of so many branches? Is it because you are using a special mode?)
• Create a repository which can be used for improving the performance
• Statistic how the complexity is in different circumstances (https://en.wikipedia.org/wiki/Time_complexity)

Hi @HHobeck sorry for the trouble,

I completed the issue with all the info that I currently have, I'll try to dig into it 'cause not sure what is causing it

Thanks
