Monitoring Prod over the last week has show some fairly long running markup calculations. We should investigate whether there is anything we can do to improve the run time on these.

Additionally, this may be a candidate for dividing the task up into small date steps. Some of our larger customers take multiple hours when running month ranges, whereas if we split this to smaller windows we could conceivably make smaller faster queries and potentially run them in parallel.

Just splitting up the tasks may be safer in itself, since we re-queue a task if it takes longer than 6 hours to complete. This means we could potentially re-queue some tasks endlessly if they are large enough to not finish in time.
