Just a follow up:

I've tested using Giovanni's dataset and the render times for me
remain more or less static from 2.14.0 -> 2.18.8, taking 18 +/- 1
second. I'm confident there's no regression there (haven't tested
master yet - that still needs doing).

Next up I'll run through a similar set of tests checking layer load
times. It's possible this is where the regression lies.
