Performance Library\r
\r
This library instance provides infrastructure for DXE phase drivers to log performance\r
- data. It consumes Performance Protocol published by DxeCorePerformanceLib\r
- to log performance data. If Performance Protocol is not available, it does not log any\r
+ data. It consumes PerformanceEx or Performance Protocol published by DxeCorePerformanceLib\r
+ to log performance data. If both PerformanceEx and Performance Protocol is not available, it does not log any\r
performance information.\r
