Slow advance after 6.5 update
After updating to 10.10 and Keynote 6.5 my Keynote response time has dropped from instantaneous to anywhere between 5-10 seconds of lag time before either starting the slideshow or advancing the slide.
This isn't transition-timing related as certified by the duration of the transition when it does happen and that starting or Escaping out of the show also take 5-10 seconds. As a test I advanced a slide, waited 10 seconds before pressing the space bar and it still took 5-10 seconds to advance to the next slide.
I tossed out the Keynote prefs files and restarted but this did not fix the problem.
