Spree Performance

Before writing code

Fetch live docs:

1. Search the Spree blog at https://spreecommerce.org/blog for performance posts (Black Friday case studies, scaling guides).
2. Inspect Spree::OrderUpdater and other "hot path" service objects in the live source for known bottlenecks.
3. Cross-reference Rails 7+ performance guides for caching primitives.
4. For Sidekiq tuning, fetch https://github.com/sidekiq/sidekiq/wiki/Best-Practices.
5. Check the v5.4 announcement (https://spreecommerce.org/announcing-spree-commerce-5-4/) for the API v3 "10x faster than v2" claim and what changed.
