(Info) DSB Coverage

Metric Description

Fraction of uOps delivered by the DSB (known as Decoded ICache or uOp Cache).

Possible Issues

A significant fraction of uOps was not delivered by the DSB (known as Decoded ICache or uOp Cache). This may happen if a hot code region is too large to fit into the DSB.

Tips

Consider changing the code layout (for example, via profile-guided optimization) to help your hot regions fit into the DSB.
See the "Optimization for Decoded ICache" section in the
Intel 64 and IA-32 Architectures Optimization Reference Manual
