Choose Resque if:

• You need multiple queues

• You don't need to persist every Ruby object ever
• You have potentially huge queues
• You want to see what's going on
• You expect a lot of failure / chaos
• You can setup Redis
• You're not running short on RAM

• You don't want to setup Redis

Choose Beanstalkd if:
