I am rebuilding the image on a Digital Ocean droplet and something takes ages: I, [2024-01-10T09:47:14.854311 #1] INFO -- : > cd /var/www/discourse && su discourse -c 'bundle exec rake themes:update assets:precompile' Node.js heap_size_limit (492.75) is less than 2048MB.

[Bild] Tomáš Znamenáček: The droplet has 1 GB of RAM I believe this will make you very memory constrained now. It’s getting to the point where I’d actually recommend a minimum of 4GB for a Discourse instance (plus swap!) (even with 2GB + 2GB swap I find online updates painfully slow).

Thank you! Unfortunately that’s about four time the price for an improvement I would probably only feel during updates. Also, the cloud install guide still says: The default of 1 GB RAM works fine for small Discourse communities. We recommend 2 GB RAM for larger communities. Do we know where the…

It’s coming from ember-cli. You’re already experiencing a time vs. space trade off (lack of memory space causes the process to take longer).

[Bild] Robert: even with 2GB + 2GB swap I find online updates painfully slow I think for my next update on my two servers, I will use the hosting provider’s flexibility to migrate to larger RAM before updating, and migrate back to my present minimum immediately afterwards. There’s a small amo…

[Bild] Ed S: I think for my next update on my two servers, I will use the hosting provider’s flexibility to migrate to larger RAM before updating, That’s very cool! Who is your hosting provider?

[Bild] Robert: Who is your hosting provider? Digital Ocean in one case (1G RAM), Hetzner in the other (2G RAM).

They both allow online, in-place increases in RAM temporarily? Or you need to shuffle between “droplets”/instances? Or just a reboot?

[Bild] Robert: They both allow online, in-place increases in RAM temporarily? No, [Bild] Ed S: There’s a small amount of extra downtime It’s shutdown - resize - start - rebuild - shutdown - resize back - start

[Bild] Richard - Communiteq: It’s shutdown - resize - start - rebuild - shutdown - resize back - start OK, but still in-place. That’s a great option, but yeah, extra hassle .. and downtime. Given that rebuilding time on a 1GB machine takes so long you might as well do this, because it’s goi…

Ich glaube, das wird dich jetzt sehr speicherbeschränkt machen.

Es ist mittlerweile so weit, dass ich mindestens 4 GB für eine Discourse-Instanz (plus Swap!) empfehlen würde (selbst mit 2 GB + 2 GB Swap finde ich Online-Updates schmerzhaft langsam).
