Notice how the active OS X builds reaches the limit of 216 jobs and the backlog of OS X jobs increases without decreasing. This is a capacity issue that is likely related to high OS X build costs.
Another thing to notice is that the backlog correlates strongly with time of day in the EST timezone, where the backlog starts to take off after 9am EST.
