sidekiq-cluster

https://github.com/kigster/sidekiq-cluster

This library provides CLI interface for starting multiple copies of Sidekiq in parallel, typically to take advantage of multi-core systems. By default it starts N - 1 processes, where N is the number of cores on the current system. Sidekiq Cluster is controlled with CLI flags that appear before `--` (double dash), while any arguments that follow double dash are passed to each Sidekiq process. The exception is the `-P pidfile`, which clustering script passes to each sidekiq process individually.
