This topic has already come up in older posts, and I think it is still very relevant. I understand that n8n itself only uses one CPU core per process. But that is exactly why Queue Mode would be useful: with multiple workers, executions and workflows can be distributed much better.

Especially when running Cloudron inhouse or on your own infrastructure, “just upgrade to a bigger VPS” is not always a real solution. Single-core performance cannot simply be increased endlessly. With larger amounts of data or heavier workflows, n8n can quickly become slow, hang, or crash.

In my opinion, Queue Mode would not even need to be enabled by default. It would already be very helpful if the official package included the required support so it could be enabled when needed.

I previously experimented with a custom version of the Cloudron n8n app, using AI, and managed to build a prototype with Queue Mode. I am not a Developper and just wandet to test if this would solve my perfomance issues wich it did. That makes me think it would be a real benefit to have this option available in the official package as well.

Overall, I believe this would make n8n on Cloudron much more robust for larger setups.
