[image] How to set Email sending speed limit? Support I have a forum on discourse but with slow sending speed limit (20/sec) Am I able to set sending speed limit on discourse? I’m asking this because I found that I got nearly 500,000 records everyday on unsub…

[image] Richie: If I watch Sidekiq I can see the “Scheduled” counter racking up all the individual emails one by one, once it gets to around 20,000 it then moves them over to the “Enqueued” tab, and then they eventually start sending out. I timed it this evening. I scheduled a post to publis…

[image] supermathie: Once the email jobs are scheduled, your sidekiq workers are working through them one at a time. Bumping up the sidekiq workers (set DISCOURSE_SIDEKIQ_WORKERS up from 5 to 10, 15, or 20 depending on server capacity) means more jobs get processed at the same time, so the queue…

[image] Richie: Can I just create that setting under the existing unicorn workers setting, then rebuild? Eg: expose: - “443:443” env: UNICORN_WORKERS: 8 DISCOURSE_SIDEKIQ_WORKERS: 7 Is it as simple as that? :thinking: Is anyone able to confirm this is the correct change to make …
