[Violation] Forced reflow while executing JavaScript took 30ms; [Violation] 'setTimeout' handler....
[Violation] Forced reflow while executing JavaScript took 30ms; [Violation] 'setTimeout' handler....

As requested, here is my sample project links:
https://datatables-php.000webhostapp.com/
https://datatables-ajax.000webhostapp.com/
I often get errors like these:
[Violation] 'setTimeout' handler took 143ms jquery.min.js:2
[Violation] Forced reflow while executing JavaScript took 30ms
Active resource loading counts reached a per-frame limit while the tab was in background. Network requests will be delayed until a previous loading finishes, or the tab is brought to the foreground. See https://www.chromestatus.com/feature/5527160148197376 for more details
Any simple ways to make it faster? Or perhaps my code just has something wrong.
Anyway, I decided to make a separate topic as this is a different issue now than my original post from here:

This is a non-urgent issue, but I do hope you get time to eventually look at it. Thanks!

What do you need to do to trigger that error on the page? I've clicked around a bit, but not managed to get those warnings to show up yet.

I got rid of a 404 warning and now the warnings violation seems to be back on the one web-page only https://datatables-php.000webhostapp.com/
The violation seems to sometimes not be there when I randomly check. Would which computer and current internet speed impact this? I have no clue
Hello, this problem is a bit old but I have the same, I will create a post if necessary
I have the same problem when I use the "ScrollX" and "ScrollY" option but especially with the "table.columns.adjust ();" (after load)
@Loulou90 We're happy to take a look, but as per the forum rules, please link to a test case - a test case that replicates the issue will ensure you'll get a quick and accurate response. Information on how to create a test case (if you aren't able to link to the page you are working on) is available here.
Cheers,
Colin
