3. Simple Scenario

4. Complex Scenario

5. Can we go over this limit?
Yes!
Queueing several syncrounous tasks allows us to go further.

6. Separation of components with
Queue Manager & Workers
Queue Manager: collects & assigns tasks to workers
Workers: execute tasks (with repeat-until logic)

7. Response time improvments
Save 30% of the time by queuing index update on product save
Magento CE v. 1.8.1.0 with sample data. Index update on save enabled. Data collected with Xhprof profiler.
