Use of RAM info


At System Info I have
Real memory 2.32 GB total, 915.33 MB used
Virtual memory 4 GB total, 221.55 MB used

while ‘top’ displays
Mem: 2429952k total, 2337104k used, 92848k free, 64424k buffers
Swap: 4192944k total, 226868k used, 3966076k free, 1253460k cached

Why such kind of difference in Real Memory.
Thanks for an explanation.


In top, when you see buffers/cache – that memory is technically available. Linux just puts it to use as cache when it’s not otherwise being used.

When showing free RAM, Virtualmin includes buffers/cache in that output.


Yep, Virtualmin is that smart. :wink:
