Storm cluster with time

[sam mohel]

 Iam a researcher and I hope  you can help me on this questions my goal is
to update algorithm that coder used to make data more accuracy. I have one
Java process that make me need one supervisor right ? When I made machine
core i5 with 8 ram as supervisor and machine core2duo with 2 ram as nimbus
I got error in GC overhead as data is huge and need more ram . I swapped
the two machines then everything worked but took long time . It took more
than 20 hours . Is it normal ? Or what can I do ?
