This probably got second-chanced or something because I posted it over a week ago. Funny that this went up here since the follow-up is probably more in-depth.

Hope people enjoy it, both the technically interesting bits and the general goofiness of it all. I personally have enjoyed making the number go up.

I hope my co-fouunder on NervesCloud does some write-up on the allocator variations he has been trying. Every day he pops in and asks me to throw 5000 devices at the servers and see what they do. mimalloc, jemalloc and some others. Those two seem to do a better job with fragmentation for the BEAM than whatever we had by default, presumably from glibc.
