Hi
(just being bored and depressed)
There are always lot of talks about HTTP/2 and how it improves performances of websites. But another revolution was the release of PHP 7, which boosted performances of dynamically generated pages. I know there is nothing new, since PHP 7 was released in December 2015, but I am still surprised to see how many webmasters are still running under PHP 5.x. So if you didn't yet make the switch, I greatly encourage you to do it, your pages will generate much faster, you'll improve your TTFB and First paint.
(the bottleneck can still be your database access, and network of course, all depends how your pages are coded too, but speed improvements are always welcome)
Beware that there are some backward incompatibilities between PHP 7.x and PHP 5.x, but not a big deals, and all these incompatibilities are about functions which have been depreciated years earlier.
I am myself running PHP 7.3-dev (yes I know you are not supposed to run a development version on a production site, but I no longer mind about anything), and it's again faster than PHP 7.2.
That's all folks,
