Occasionally we run in to problems with certain tasks in Luminate taking longer than usual to finish. Tasks such as generating an email audience, Queries, Reports and downloads are stuck in queued or not available for an extended period of time. Why does it take some tasks longer than normal to finish?
Each of these processes (emails, syncs, reports, queries, etc.) are run by Tasks in Luminate on the back end. There are only so many tasks that the servers can run at any given time. If you and your colleagues are triggering a lot of tasks to run on your system all at once, only a few will run at first while the rest remain queued. Being that you cannot always see what your colleagues are running, it may appear to you that everything is pending when in fact your colleagues tasks are running and yours are waiting for them to finish.
Once these objects start running, they can take longer to run than expected. Even if the object seems to be small, it may require more resources than you expected. In cases like this, the long wait is due to a larger queue.
During peak hours of the day, which is midday on weekdays, the servers can have a heavy work load, which will make everything take longer than if you were to run these tasks at night or over the weekend. On average, if it takes less than 2 hours for a task to start running and less than 4 hours to complete, that is fairly normal for midday weekdays. If you have mission critical tasks that need to be run, it is recommended that you schedule them to run during non-peak hours. Contact support if you can't find a way to schedule these tasks; most of them can be scheduled somewhere in the product.
