Originally asked at Reddit.

Chris McCord created 2 million concurrent connections on 40core/128gb Box. Those were not requests per second, but persistent live connections. I don't know if those connections were doing something, or were idle.


Edit: I read that they were sending a wikipedia post to all of those 2 million connections, so the connections were not idle, but actually doing something.


I also don't know how fast phoenix's views are, or how efficient it's database library and the mechanism is. I also don't have any real world experience of using phoenix.

So those of you who have used it in production, not just on Heroku, but also on VPSes, Cloud servers and Dedicated servers, how much load will phoenix take on $80/mo Linode VPS, if the application is served as html (not json) using phoenix_html or turbolinks?

The configuration of this VPS is:

  • 12 GB RAM,
  • 6 CPU Cores,
  • 192 GB SSD Storage,
  • 8 TB Transfer,
  • 40 Gbps Network In,
  • 1000 Mbps Network Out
