Gem Version Build

Simple, efficient background processing for Ruby.

Sidekiq uses threads to handle many jobs at the same time in the same process. It does not require Rails but will integrate tightly with Rails to make background processing dead simple.


Version Latency Garbage created for 10k jobs Time to process 100k jobs Throughput Ruby
Sidekiq 6.0.2 3 ms 156 MB 14.0 sec 7100 jobs/sec MRI 2.6.3
Sidekiq 6.0.0 3 ms 156 MB 19 sec 5200 jobs/sec MRI 2.6.3
Sidekiq 4.0.0 10 ms 151 MB 22 sec 4500 jobs/sec
Sidekiq 3.5.1 22 ms 1257 MB 125 sec 800 jobs/sec
Resque 1.25.2 - - 420 sec 240 jobs/sec
DelayedJob 4.1.1 - - 465 sec 215 jobs/sec

This benchmark can be found in bin/sidekiqload and assumes a Redis network latency of 1ms.


  • Redis: 6.2+
  • Ruby: MRI 2.7+ or JRuby 9.3+.

Sidekiq 7.0 supports Rails 6.0+ but does not require it.
