I run a small xenforo forum for a lotro kinship/guild (under 100 members on forum), the site has about 100k posts, but rarely has more than 6-7 people online at once due to timezones etc.
I'm running on shared server with almost 8.000 users, sometimes 100 online, over 12.000 posts. It runs well so far, but it's true I can't run all add-ons.

Not to advertise vps.net as I don't like their shared server/cloud site still on php 5.2 when I'm using them last 2013 but, with the $20 per month here: http://vps.net/products/cloud-sites it handles very fine my forum with 200-300 simultaneous members online and almost 1K guest.
The most important thing with low memory if for all processes to be carefully configured so that the system does not crash when it runs out of memory. This could happen due to a robot, hacking attempts, etc.
