Throughput Time (w/o collees)

Top deviated metric shows the functions that have the biggest change in absolute execution time (throughput) — i.e., the functions with the largest delta in execution time.

This metric identifies functions with the most significant self-time degradation — execution time spent exclusively in the function itself, excluding callees. By leveraging segment-based time prediction and respecting call-site boundaries, the report isolates function-level performance regressions with higher accuracy.

The report focuses on functions that take the most execution time on their own and ignores time spent in child functions (callees). The time spent in callees is dropped by how assembly segments are sliced in our processing and how the LCLM model is trained: we predict time on segments and then calculate the time without callees. Assembly segments in our processing never cross function call-site boundaries, which enables this isolation.
