Scrum for Trello causes severe performance issues #112

Hi there, I work on a Trello Power-Up. At least one of our users was having very poor performance with our Power-Up and we tracked it down to the Scrum for Trello extension. They really like your extension, but the performance hit is pretty severe. To give you an idea of the performance impact, here are two profiles for opening a card from the time that the card is opened to when the Power-Up section for our Power-Up appears.

Much of the time is spent in jquery in response to timer events. It seems like Scrum for Trello is doing a lot of work, doing it often, and mutating the dom often enough to cause significant churn/paint invalidations ([unattributed] in those charts).

Would it be possible to turn down the frequency of updating and/or not invalidate the layout as often? It would be great for our users to be able to have a snappy Trello experience and get the benefit from both of our add-ons. Thanks!
