parallel-fs-ops.template.yml (2.8 KB) Let’s talk about a scaling problem that becomes painfully obvious once a Discourse site accumulates a large upload library. What used to take minutes for a chown command to run across a huge uploads directory now takes seconds! Background Discourse rebuilds c…

Nice. I guess that’s why S3 and CDN are things.

Yup. But not everyone wants to add that complexity. I kind of am using S3/R2/B2 via using JuiceFS. That way it mounts locally like a real file system, and no worries. And then Cloudflare caches the assets that way automagicallly.

Should this instead be a PR that changes the templates doing the chown?

Yes please! I’ve moved this out of Wiki and back to Support > Self-hosting , since it’s not really a pattern we want to encourage everyone to handle manually. If there’s a safe performance improvement we can make in the upstream template, let’s do that! I don’t think we’d want to override the syste…

Let’s try a simpler version first. This doesn’t run anything in parallel, but it does skip the chown for files which already have the correct permissions. It’s a pattern that we’re already using elsewhere in discourse_docker: PERF: Skip chown for f…
