Branch Resteers

Metric Description

This metric represents cycles fraction the CPU was stalled due to Branch Resteers.

Possible Issues

A significant fraction of cycles was stalled due to Branch Resteers. Branch Resteers estimate the Front-End delay in fetching operations from corrected path, following all sorts of mispredicted branches. For example, branchy code with lots of mispredictions might get categorized as Branch Resteers. Note the value of this node may overlap its siblings.
