I have been a very happy WP Rocket user for a couple of years now, but I thought I would give Hummingbird a spin to see if it stands up to WP Rocket. I made a very simple test on https://wayout.no/ where I first ran the site with WP Rocket twice on https://tools.pingdom.com/ (I have had WP Rocket running on this site for two years now), and then I deactivated WP Rocket and installed Hummingbird, ran first one test, then smushed images (I have been using wp smush pro a long time, just needed to smush 20some last images added) and ran test two.
I got the same preformance grade on all teste, 78. But the load time differed a bit. the first run on WP rocket gave me a staggering 2.65sec load time, but the second gave me 534ms. The first hummingbird gave a 787ms and the second gave me 553ms.
So to the questions:
- If I also get around 2.65sec on an uncaheed run with Hummingbird, is this critically bad?
- On Hummingbird it gives a poor 30/100 on "Remove render blocking resources". when I click "Improve score" I get the overview message "Your page has 1 blocking script resources and 6 blocking CSS resources. This causes a delay in rendering your page."
clicking on "CONFIGURE SCRIPT DEFERRING" gives me a long list of files, but two with red text warning:
Error: This file included in your output can't be minified or combined
Error: @import directive is not allowed in stylesheets
What is the correct approach to fix these?
