It is nothing in a lot of devices, I would say 75% will parse and execute in under 50ms.

But that other 25%, the phones with little power may take 100+ms just to parse and execute jQuery.

And that is just jQuery without it doing anything.

Come May when the web vitals update rolls out that extra few ms could add up to thousands for a mid sized firm in slight position losses on Google.

Personal project with 0 traffic..jQuery away. E-commerce site doing 500k+ a year, optimise the hell out of it and dropping jQuery is a definite quick win!
