-  Performance Library\r
+  Performance library instance used in PEI phase.\r
+\r
+  This file implements all APIs in Performance Library class in MdePkg. It creates\r
+  performance logging GUIDed HOB on the first performance logging and then logs the\r
+  performance data to the GUIDed HOB. Due to the limitation of temporary RAM, the maximum\r
+  number of performance logging entry is specified by PcdMaxPeiPerformanceLogEntries.  \r
