This issue might be a duplicate of existing issues. Please check:

  • #9059: High CPU Utilization Due To Repeated Git Process Invocations - OpenCode makes thousands of 'git show' calls in a loop causing very high CPU usage
  • #6172: High CPU usage (100%+) during LLM streaming in long sessions due to O(n) text buffer rendering - Detailed analysis of CPU spikes reaching 100-117% sustained during streaming
  • #8887: [BUG] Snapshot module ignores 'watcher.ignore' config, causing excessive disk usage and performance degradation - Git add processes cause high CPU and I/O during every agent step
  • #5220: Glob search uses 100% of CPU - ripgrep/glob operations consume 100% CPU
  • #6741: perf: ripgrep config file search scans entire home directory including large hidden directories - Causes 1000%+ CPU on home directory scans

Feel free to ignore if none of these address your specific case.
