VSZ is VmSize i.e. virtual size, not physical RAM.
It matters only if it's actually used.

Best tool available for N810 for looking into whole system memory
usage is propably sp-smaps-measure/sp-smaps-visualize.  Install
those packages from the SDK tools repo[1] and then do:

* On device:
     sp_smaps_snapshot > smaps.cap
* On Sbox:
     sp_smaps_analyze smaps.cap
* On Desktop:
     firefox smaps.html

N810 version of sp_smaps_analyze might still be the Python version,
not C-one like the Fremantle one, and the produced HTML data is pretty
large, that's why I think it's better done on (e.g. x86) Sbox.

The produced HTML tables are better viewed on Desktop, device screen
is a bit too small for them.
