There are a bunch of such systems. https://sdf.org/ has been doing it for decades now, as has M-Net and formerly Grex (which got shut down on April 15 of this year). > > Not quite a thousand users logged in simultaneously, but half that.

This was from the output of `top` and `htop`; if SMT is in use, Linux generally reports those as separate LPs, so I'm going to assume that if it only lists 6 CPUs, there are only 6 logical processors (either 6 cores with SMT disabled or 6 virtual CPUs; I don't know if it's a VPS or what). > But still, six contemporary CPUs could be a lot of computing power. > > 16 GB of memory is nothing to sneeze at, especially for running commands > in a CLI environment. -- I'm assuming no daemons saying FEED ME RAM. I think they run a fairly robust web presence including a Mastodon server and some other stuff as well; I see postgresql running, a bunch of other random stuff. Curiously (or not) no SMTP service. I'm told they run a Gopher server, which seems like a waste of time to be, but hey: to each their own. > > It's surprisingly zippy. > > I applied for membership.
