Metric Description

This metric represents a fraction of cycles during which CPU operation was limited by the LSD (Loop Stream Detector) unit. Typically, LSD provides good uOp supply. However, in some rare cases, optimal uOp delivery cannot be reached for small loops whose size (in terms of number of uOps) does not suit well the LSD structure.

Possible Issues

A significant number of CPU cycles is spent waiting for uOps for the LSD (Loop Stream Detector) unit. Typically, LSD provides good uOp support. However, in some rare cases, optimal uOp delivery cannot be reached for small loops whose size (in terms of number of uOps) does not suit well the LSD structure.
