Why the tasks queue of Dashboard is growing slowly?
I've installed Puppet-Dashboard on a physical server, with 4 CPU, 16Gb RAM, and SSD hard drive. Dashboard work with passenger, and I have 4 works for delayed_job.
But the pending tasks queue still growing after 15-20 min, and I have to clear jobs after one hour. What can I do? What things I've missed on my dashboard installation?
