Branch Resteers

Metric Description

This metric represents a fraction of cycles while CPU was stalled due to Branch Resteers. Following all sorts of mispredicted branches, this metric measures the delays of fetching instructions from a corrected path caused by the frontend of the machine. For example, branchy code with lots of (taken) branches and/or branch mispredictions can be categorized under Branch Resteers.
