Performance degradation in google-api-core #16552
Description
Determine this is the right repository
- I determined this is the correct repository in which to report this bug.
Summary of the issue
Context
Upgrading google-api-core from version 2.27.0 to 2.28.1 (and later) has caused a significant spike in CPU usage. While version 2.27.0 maintains a steady 20–40% utilization, versions 2.28.1 and above consistently reach 100% CPU consumption.
Expected Behavior:
Same consumption of CPU as in 2.27.0
Actual Behavior:
CPU consumption increased up to 5 times.
