-# 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
