Apache Sqoop Export Performace did not enhance When the number of PM from 2 to 4

Hi,

     

   when I add 2 PM ,the performance seem did't enhance. How can I tune the performance when I add more PM ? can you tell me How the UM dispatch the tasks to all the PMs . How I can optimize the procedure . Are there some XML files that I can configure my InfiniDB system to promote the efficient of all the PMs???
