Subject Re: something about memory usage
Date Thu, 01 May 2014 01:53:12 GMT
Hi, daniel, thx for your help

  i'am just running 1 core slaves. but still i can not work it out. the
executor does the task one by one,
  task0, task1, task2...

  how can i get the memory task1 used with so many threads running in the
background, also with GC.

  it's not accurate to use Runtime.getRuntime().freeMemory
