Having both available is a huge win for the Rails ecosystem.

If you’re just starting or have a small project Solid Queue is invaluable and reduces costs and friction.

If and when you need more performance or power Sidekiq is still available. Both run in the context of your Rails app so moving jobs from one to the other shouldn’t be terribly hard.

Yes. But as with all things Rails I do wish the default performance could be pushed a bit. So say Solid Queue could work for 90% of project instead of 70 - 80%.

May be ZJIT could help.

Exactly, it's not an either/or situation. I've worked on a codebase that did 3-4k/s jobs through sidekiq and in this case sidekiq is obviously the best option (although we also used a go sidekiq client for certain tasks that didn't need the rails app context) but using sidekiq from the beginning is premature optimization. You can easily start with Solid Queue and switch over to sidekiq when you actually have data that tells you that it'll potentially become a bottleneck. Premature optimization is a complexity cost.
