Bamboo Trigger Delays

[Reuben Schloeman]

We have several users using the new Bamboo Trigger feature.  Most of them are complaining that the Scheduled Trigger's are not firing at the scheduled time(s).  The delays are anywhere from a 20 - 50min or greater.  This time delay is unacceptable for most users.

We are using Schedule by Time and Cron Expressions.  I don't think there is a quiet period in the repos because some of the plans that are delayed are not even using a repo. So, I think a quiet period is not the issue.

The Agents and the servers are on the same Time Zone. I don't understand the reason for these time delays. 

Can you please help me figure out a solution to this to minimize the delays as much as possible? 

Or at the very least explain why Bamboo may be causing these delays and give me a formula that estimates how long the delay may be?
