v5 beta 16 renders large item lists very slowly #451

Closed CameronNemo closed 2 years ago

CameronNemo commented 2 years ago

Hello,

I have been trying out v5 beta 16 and I noticed that large items list can take a second or three to render. I am not using debounceWait or loadOptions (I did try setting debounceWait to 10000 to rule it out; it had no effect).

I was unable to try from the tip of feature/v5 because npm installing from the branch (npm install git+https://github.com/rob-balfre/svelte-select#feature/v5) did not work. So I apologize if this performance issue is fixed.

Thanks.

@CameronNemo remove virtualList, instead use the named slots provided... see migration guide for pointers.

Any issues and i'll try to put an example in the docs. Let me know, thanks!

Hmm so I really don't know what happened but it seems like it sped up overnight. Which does not make sense. But I guess if it ain't broke.
