Footable with jQuery 3.x is very slow - with 2.x is fast

[Akron99]

I tested it with only 100 lines. The rows load (rendering) is significantly slower. And paging and searching are also slow.
I changed the jQuery library to version 2.x and it became lightning fast. The speed difference is approx. 10-20 times (I didn't measure it, only an estimate. well perceptible difference).

this is due to the Deferred method. It contains a call to the "window.setTimeout" function, and it is slow.
