OmniGraffle 7.11 for Mac is a very important update — it includes significant performance improvements. There’s no silver bullet for making an app faster: there is only figuring out which things are slow, figuring out how to speed those things up, figuring out how to measure progress — and then making sure no new bugs were added. It’s a lot of work!

In this special episode we have two separate interviews. The first is with OmniGraffle engineers Rey Worthington and Shannon Hughes. The second is with Ken Case, CEO; Tim Wood, CTO; and Dan Walker, OmniGraffle PM. These interviews were recorded while the work was in progress but pretty far along.

We talk about how we found the slowdowns, how we fixed them, and how we wrote tests to make sure we know we’re making OmniGraffle faster.
