We have an #Announcements category in which all our members are automatically subscribed to watch the first post. This allows us to schedule the publishing of posts in to that category on set times/dates. In turn, the announcement is then emailed to around 25k members. The problem we face is that…

[immagine] 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 pub…

[immagine] 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 qu…

[immagine] 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 ma…
