Terragrunt with/without cache very slow

[joshbsemperis]

Describe the bug

Since upgrading to Mac OSX 15.0 i have had very slow terragrunt run times, minutes for what used to be not even seconds. I am currently using Apple Silicon, if thats relevant. Running the TF state lock and release with Azure Blob is getting stuck and sometimes takes 5 minutes to lock or release.

Versions

• Terragrunt version: terragrunt version 0.67.12
• OpenTofu/Terraform version: Terraform v1.9.6 on darwin_arm64
• Environment details (Ubuntu 20.04, Windows 10, etc.): Mac OSX 15.0 Apple Silicon

Hi,
try running with --terragrunt-log-level debug to get more insights on what it takes more time to execute

More insights how to debug execution in:

FYI, we're seeing this with other users as well. For anyone who has access to the Gruntwork Community Slack workspace, see https://gruntwork-community.slack.com/archives/CHH9Y3Z62/p1727904354746019.

We are also observing in the recent version a performance degradation, it seems related to #3441 or some other caching mechanism is not working properly

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
