   > It is complicated, there is too much information in profile. For example if you want to increase the parallel, you can adjust the replica num or `parallel_fragment_exec_instance_num`
   Emm...no need to explain all configs about profile, maybe some typical cases needed.  For example, in this page, `http://doris.apache.org/master/en/administrator-guide/config/fe_config.html#configurations`, there is only one row about `parallel_fragment_exec_instance_num`, I can't know what is an empirical value or what value can perform better performance, 10 or 100? So I am looking forward to tidy up some true cases and provide some practical experience according to these cases.
