Is WordPress with Gutenberg block editor slower than old WordPress Classic Editor?

WordPress Mobile Speed


There are no affiliate links on PagePipe.

WordPress version 5.0.3 core is 20 milliseconds faster that 4.9.8.

Is that significant?

Not really.

So Gutenberg isn’t slowing anything down? Nope. Not until you junk it up with features and decoration that no one needs. Then it’s slow.

Discipline. Caring.

Thanks for asking.
