question about memory
|
Zhoutianran <zhoutianran@...>
Hi,
I am from the NEMO project. When we integrating the OF plugin in our project, we found it will consume a lot of memory. It works only when I set -Xmx4GB, and the VM memory to 4G. That will impacts our demo deployment. I used nox, and implemented a private openflow controller before. I am very curious about why the OF plugin need so much memory. Is there any possibility to optimize? Could anyone from this mailing list can help me? Thanks, Tianran |

Memory consumption depends mostly on operations of your application and data set used by your application. In order to better understand this issue, heap memory snapshot would be useful to understand what is consuming lot of memory. Tony -----Original Message-----

Hi Tony,
Thanks for your fast response. But the error occurs when we try to install the of plugin feature. Our application have not been installed, and of course no flow table submitted. I can provide a snapshot when we first meet this problem several months ago.
We sent the problem here then, and got the solution was to set -Xmx4GB.
Now, I have time, and want to know why J
Best, Tianran
