The default Essex Nova scheduler is slow when it comes to scheduling multiple VMs. Taking about 26 seconds to schedule 100 VMs in our lab environment.  This talk will cover the process we took to identify the bottlenecks in the scheduler, in both the Essex and Folsom schedulers.  Covering:

  • profiling Nova
  • how eventlet changes everything
