Yup, I have to say, I'm noticing improved performance across all 3 major platforms I browse the site with. It's worth noting that I no longer have that awkward bug where the page background would load, followed by the content itself a minute or so later. I can open pages in tabs and know they'll be there by the time I click on them.
I'm not sure why you'd be finding the site slower GP- in my experience this is the fastest the site's been in years.
