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