Since Workarea 3.3,
Workarea::Configuration::Sidekiq manages the configuration of the Sidkiq server programmatically. When necessary, set
WORKAREA_SIDEKIQ_CONCURRENCY in a particular environment to control concurrency (consult with Workarea Hosting as needed).
Earlier versions of Workarea depend on a Sidekiq configuration file in the application at config/sidekiq.yml. Make configuration changes in this file when necessary.
