performance advice

[Nyx2022]

hello, i'll push 1000 rows into data at a short time with multi rotate which has interval between rotates,and the grid's columns are customed and complex, i found it is very slow,when i add the 8th 1000 rows into data,it has only 1000 in ui,i've used async and await,so can you help me to optimize,if it acutally , i advise grid to use worker or webgpu to solve it,thank you

I'm also having the same issue with dynamic data. It's definitely a performance problem, but it's related to Svelte's reactivity. I solved it by using $state.row inside a class, and now I can add 20k rows without any issues. I hope you're also using Svelte 5 Runes, and that this helps you.

If you show your code which loads the data I can try to optimize it.

i found the ui lag is very obvious in v2.4.0,neither in call add-row nor by data.ubshift;data=[...data]
even the data is small

Please try "svelte": "5.45.8"

Please try "svelte": "5.45.8"请试试“svelte”：“5.45.8”

i found the ui lag perhaps for my custom cell is complex,which has some loop process to set value on row,when i change the logic,the scroll progress is very smooth,but the the toggle of treemode is still slow
