-# Component description file for DxeCore Performance Library
-#
-# This library provides intrastructure for DxeCore to log performance.
+# This library provides the performance measurement interfaces and initializes performance
+# logging for DXE phase. It first initializes its private global data structure for
+# performance logging and saves the performance GUIDed HOB passed from PEI phase.
+# It initializes DXE phase performance logging by publishing the Performance Protocol,
+# which is consumed by DxePerformanceLib to logging performance data in DXE phase.
+# This library is mainly used by DxeCore to start performance logging to ensure that
+# Performance Protocol is installed at the very beginning of DXE phase.
