Ever since ansible-core v2.19 we’ve seen a major (>10x) performance regression in using inventory cache.
There is this existing issue on GitHub:
- 2025-12-03: https://github.com/ansible/ansible/issues/86292
I have used cPython to profile real world usage of 2.18.19 (fast) vs. 2.21.3 (slow), but I’d like to not share that info publicly in case it contains data that should not be shared publicly.
@shertel: How can I share this data with you or all the contributors in a non-public way?
