Vaadin 14. Grid. IE11

Hi, all.

Vaadin 14 very slow rendering grid(create DOM) with lazy loading in IE11. 200 row x 35 columns.

Chrome load all page 6.5 sec.

IE11 do it 1.5 min.

Can i do something?

If I set 15 columns count, the result becomes about 15 seconds in IE.

More columns… more lags.

Are you using components inside the Grid? That will come with a performance hit for sure.

I has buttons in header row (one button → one column).
I hasn’t another components or custom renderers.

I run a perfomance debug in IE it spend all time for rendering(appendChild and other).
