So after we’ve extended the virtual cloud server twice, we’re at the max for the current configuration. And with this crazy growth (almost 12k users!!) even now the server is more and more reaching capacity.

Therefore I decided to order a dedicated server. Same one as used for mastodon.world.

So the bad news… we will need some downtime. Hopefully, not too much. I will prepare the new server, copy (rsync) stuff over, stop Lemmy, do last rsync and change the DNS. If all goes well it would take maybe 10 minutes downtime, 30 at most. (With mastodon.world it took 20 minutes, mainly because of a typo :-) )

For those who would like to donate, to cover server costs, you can do so at our OpenCollective or Patreon

Thanks!

    Yes. It’s called performance testing. Basically an engineer would need to setup test user transactions to simulate live traffic and load test the system to see how everything scales, where it breaks, etc. Then you can use the results of the tests to figure out how big of an instance you should use for your projected number of users.

    Jmeter, and locust.io are the two biggest open source performance test tools.

      Worth noting that typical app scaling does not scale linearly, and hardware caps out at some point (with diminishing returns up to that point) - federation will help with that much cheaper where normally a company would just have to throw more money at more servers themselves :)

        Yup. You don’t have to explain that to me. It’s funny when folks assume:

        if I double the servers, I’ll get twice the throughput!

      Yeah, I meant specific data using lemmy.world as a datum, not the theoretical “check and see if you guessed right” method.
