General Retirement

Metric Description

This metric represents a fraction of slots during which CPU was retiring uOps not originated from the Microcode Sequencer. This correlates with the total number of instructions executed by the program. A uOps-per-Instruction ratio of 1 is expected. While this is the most desirable of the top 4 categories, high values may still indicate areas for improvement. If possible focus on techniques that reduce instruction count or result in more efficient instructions generation such as vectorization.
