I looked at a profile for this. I ignored the page load and only considered the time taken to add a new slide to the end of the document. Chrome is noticeably faster to add a blank slide. We take about 200ms to add a new slide, and Chrome is near instantaneous. We're spending about 10% of that time doing reflow on SVG boxes, and the remaining time seems to be spent running interpreted JS.
WONTFIX for now to limit perf benchmark bugs to high impact. Please re-opened when new input latency metrics landed and confirm this issue.
