Random piece of information for scheduled e-mails:
GoodData (Jan Pradac): with our current hardware we handle up to 1200 dashboard exports / 30 min. If you'd like to schedule sending dashboard by email for 2500 users, please fragment it to more schedules with max e.g. 500 users (scheduled one after another with 30 min. step). You'll handle all users during 3 hours.
Above numbers are based on average of all projects so for this particular project it could be faster/slower. We could adjust the max. number of users according to specific performance after you'll have it online.
