Magento 2 Luma top menu loads very slow
cptX opened this issue · comments
Preconditions and environment
- Magento version
2.4.6 - Anything else that would help a developer reproduce the bug
Steps to reproduce
Load the home page in Luma theme from a pc. You will notice that the menu is ready for clicking only after everything is loaded in the page. If you have many images or other stuff in the front page and in a very slow connection this is significantly noticeable and gives the feeling of a very unresponsive and slow site.
Expected result
Menu should be ready immediately after the first page draw.
Actual result
Top Menu loads very slowly because it is javascript dependent and its javascript is probably loaded at the end of the page.
Additional information
I don't understand why the top menu is javascript dependent in Luma Theme? It is so simple that it should be pure html and php, we don't need js at all here.
Also, the corresponding js probably loads after everything else in the page making the menu very unresponsive and slow. Any suggestions to make it pure html?

Hi @cptX ,
Thanks for reporting and collaboration.
Verified the issue in magento 2.4-develop instance and the issue is not reproducible.
Steps to reproduce:-
1.Add many images, videos and other stuff in the front page
2.Load the home page in Luma theme from a pc.
3.Verify if the loading is very slow and gives the feeling of a very unresponsive and slow site.
Its not significantly noticeable, magento with without videos. images, banner, slider has the same loading time as magento without anything.
In the video 1st i am showing loading of magento without anything, in the 2nd it has many thing on home screen

Probably you didn't get my point. The issue is that the top menu is javascript based and is slow loading after the whole page is finished. In your video you should focus on the top menu and wait to see when the drop down arrows will be visible and available in the top menu. Then you will realize that they are slow, the menus not the whole page. Your video is just scrolling down so it doesn't show my point.
I'll send you a video in the next days from a slow computer to show you the issue.
Hi @cptX ,
Thanks for reporting and collaboration.
Can you send the video evidence that you have mentioned above ,to speed up the process in this issue.
Thanks,
Hi, I'm uploading here the video that shows that the top menu is ready only after several seconds and after the full load of the page, leaving the menus unusable during this time, in a slow machine or in a slow connection. The video you see is through a 100Mbps connection but on a slow dual core machine. It's clearly visible that several seconds are required in every page load until the top menu is usable...
