The blog that you are currently reading has a perfect PageSpeed score 100 / 100. Unfortunately, no it doesn't. The page that has this blog post scored 95 in performance for mobile in one run and 86 in the next. It scored 91 for desktop. They'd get a higher score by adding text compression and by serving static assets (all of them?) with an efficient cache policy.
Weird, shows up as 100 for me... I'll look into that though! Thanks for heads up!
PS I get 100 consistently for your home page, so maybe you have an optimization there that can be replicated?
