+The xcatperftest command runs commandes defined in a command list file and get their execution response time baseline for performance purpose.
 The xcatperftest command is part of the xCAT package xCAT-test, and you can run it standalone or leverage it to build up your automation test cases.
 
-Any commands could be defined in the command list file, however, it is recommended that the one-time initial configuration are well prepared prior to run xcatperftest command.
