Adequate RAM? (How to determine)
I have a Readynas Duo v1. I am interested in putting on a couple more add-ons above what I have already put on. In particular the own cloud 4.0.7 add-onwhich requires the PHP 5.3 add-on. I am running the latest firmware for the Duo v1 and I use the twonky-media 6.0.38 and the Rsnapshot add-ons.
Given that the Duo v1 has 256MB of RAM I am wondering if it is adequate for running the owncloud and php add-ons in addition to the other ones I put on.
Is there a way to tell what memory usage each add-on takes?
What are the consequences with the add-ons using too much memory?
Is there a tool (I have command line access via SSH) I can use to see current memory allocation?
Any other recommendations for proper stream-lining of memory usage on the Duo v1?
Thanks,
Brad
