[nos-bbs] rough JNOS physical memory usage anyone ?

[Maiko Langelaar (Personal)]

For Proportional Set Size (PSS), you can try :

    bash-5.1# cat /proc/9110/smaps | grep Pss

Add up the columns, just note if any programs sharing
the memory exits, the PSS of remaining procs may go
up because shared memory how divided amount fewer
processes. Hopefully I quoted that correctly.

So in my case, it's closer to just 2000 KB, NOT the almost
6000 KB reported in the RSS field. The 2 MB is much more
accurate then 6 MB usage value, according to the literature.

There is tons of info online on how to do this, quite interesting actually.
