Slow performance on Lightning page on Winter 18

Hi Zach … did these optimisations make it into a release?

I’ve been doing some testing of Skuid pages in Visualforce vs Lightning and I’m seeing a significant slow down in Lightning. In one example, I took a visualisation-heavy Skuid page in Visualforce, kept the same models, but stripped out over 50% of the components and stripped out all the Javascript. The page consistently runs in 2.5 sec in Visualforce, but nearly 4 sec in Lightning.

I’m on Millau 11.2.8, so maybe it’s improved in later releases?
