extract_hottest_functions
annotations: none low

Parses a V8 .cpuprofile file and returns the top N functions ranked by exclusive CPU time (self time).

profile_path string
analyze_call_tree_path
annotations: none low

Finds all callers of a specific function in a V8 CPU profile and returns how often each caller invoked it.

profile_path string
correlate_source_code
annotations: none low

Maps the hottest functions in a V8 CPU profile back to their original TypeScript source locations

profile_path string
analyze_gc_pressure
annotations: none low

Analyses a V8 .cpuprofile for garbage collection overhead.

profile_path string
diff_profiles
annotations: none low

Compares two V8 .cpuprofile files (before and after an optimization) and returns per-function

before_profile_path string
analyze_async_bottlenecks
annotations: none low

Detects event-loop overhead in a V8 CPU profile by identifying V8 internal frames
