Topic: Optimal ammount of RAM for SME Server 9

[frank.etzenbach]

i have a SME Server running as "server only" pure Fileserver for 10 users

The machine ist a Intel single core 3,00 GHZ and 2 GB RAM.

Does it have an effect to add more RAM ?

Thanks

There is no one correct optimal amount of RAM.
It depends on the load on your server ie how many processes are running & how much RAM they each use & so on.
Note that Linux will try to use all available RAM, so if you see your RAM fully used, then be happy as that is a good thing.

A common rule of thumb is to see how much swap memory is used,
& if it is half or more than the amount of physical RAM, then you should add more physical RAM.

Check memory usage (ideally at busy times) with
top
top -i
&
htop

More would usually be better, SME will use for file cache anything not directly in use by a process. Is your SME the 32-bit or 64-bit variant? You'll find lots of spirited discussion as to whether a PAE 32-bit kernel will actually allow you to benefit from >4GB RAM.

That said, you'll see more observable benefit from the fastest NIC and network you can get, and certainly from use of SSDs.
