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.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
