ZCA Bootstrap 4 Template [Support Thread]

[lat9]

I have had a couple of clients say that Google reports slow loading from the Bootstrap template in mobile mode. Do you have any thoughts about this?

What Google tool reports this 'slow loading'?

Sorry should have been more specific:

https://pagespeed.web.dev/analysis/h..._factor=mobile
shows a score of 85.

if you click the Desktop tab, it shows 99.

220 test site with PHP 8.4 gets 94, 100, 93, 100 using incognito Chrome browser. 81, 100, 89, 100 using regular.

The culprit in this case is Grammarly. Perhaps you have something similar happening.

This is 2.1.0/PHP 8.3. But incognito scores are the same as regular browser tab scores for me.
Question though - are you using Bootstrap in your 2.2.0 test site?

Google prefers a LCP <2.5s which is hard to reach for phones from the Stone Age with 4G throttling and CMS with a lot of of js.

You still could try to enhance the server capabilities to reduce TTFB, to deliver locally and pipeline ALL css and js files. If the host is quick, it's quicker than CDN.

The js is most awful. 1kb js is always times more dreadful than 1kb of anything else. I tried to rebuild jquery with grunt but there always something from the jquery that was needed by zen cart. So no possibilities there and still one of the best js collection libraries.

Your shop is loading various of images. Though the main imag is >80kb thats's not too bad.
But you have lots of thumbnail images. All these want to be exeuted by the fucky js

And mobile has even more of that to handle menu etc.

Just to add.
The site needs 1.5s TTFB from Stuart to LA
My site needs 1.5s to LA, too. But from Berlin which is 3 times that far - and behind the ocean.
Though only 300kb instead of 450kb full page size it of course needs longer to finish at this distance and Stone Age Moto G mobile with 4G.
But I'm sure you can reduce TTFB and enhance the score for mobile too.

Yes, and running into a lot of fun with the pID thing and 8.4 glitches with several mods.
