Is 256MB RAM enough for a VPS server to run some Drupal-based websites with e-shop module ?

It is enough to "run" nearly anything in the LAMP world.

It is not enough to handle more than a certain amount of load. How much depends on the app, and could be anything from 1 to tens of concurrent users.

And of course, the OP would have to benchmark it himself to find out what those specifics are! :) – Andrew M. Sep 9 '10 at 13:19

Good enough to start with. Surely your VPS vendor will be able to upgrade your VPS if you find you need more - all you need to do then is reboot to get the extra memory.

You can probably install it, but I would recommend against using so little. Unless of course you don't have much content and/or very few views. I don't have hard numbers for you, but you may have to resort to performance testing to determine your needs.

How few is very few views? Some people might consider 10,000 very few. For many very few is like 5... Static content isn't very memory hungry. Dynamic content might be, but again depends on number of visitors. – dunxd Sep 9 '10 at 13:25
Thanks for the input, but this is fundamentally the same answer as Luke404's answer... I added a note that performance testing would help evaluate need. – gWaldo Sep 9 '10 at 13:31
