Lists Render Extremely Slow (Unbearable beyond 100 items on desktop)

[jdinard]

Lists render extremely slowly a simple render of 100 list items (each with a checkbox) takes over 1000ms to render on my desktop. Even when removing the checkboxes, I get similar performance.

On my phone (Galaxy S5) it takes nearly 1000ms to render 10 items.

Presently this makes lists unusable in many use-cases. The same list, rendered with just html and css markup, takes less than 100ms to render.

Tested in up to date version of Chrome, and Android 4.4

I'm having the same issue with performance in lists.

I suggest you to use https://github.com/orgsync/react-list

I'm using material-ui and I need a list so I'd really prefer using the material-ui list and not yet another library..

+1 for fixing this performance issue.

I'm running into this performance issue too. I'm working around it using an infinite scroll component like @oliviertassinari suggested, but a real fix would be a huge help.

@t1mmen Using react-list is not a "hack" if you need to render a significant amount of ListItem. How many ListItem are you rendering?

[t1mmen]

@oliviertassinari I've been noticing decreased performance using ListItem's starting around 10 items (on desktop). Once I get closer to 50 it's pretty painful, particularly in dev/debug mode (production is better, but still very noticeable)

Typically, around 30 ListItems are visible on screen at the same time, so there isn't a lot of room to optimize. react-list did make a world of difference when I tested with 300 ListItem's though.

You are confirming what @alltom was saying. We need to do something.

Thank you, appreciate it! As I'll be using more of material-ui in the coming weeks, I'll try to contribute more concrete reports & code in the future. Thanks again for your efforts!

I encounter the same issue with more than 10 ListItem with checkboxes (using LeftCheckbox). All the items are rerendered when I check/uncheck a checkbox in the list. The expected behaviour would be that only the item checked rerender I think.

+1 this is becoming a major issue! Any headway on a solution?

Lists are terribly slow on cordova on Android as well. I have 25 items on my list and its painfully slow even to scroll the list.

I only seem to have issues with list performance if using nested items. For me, replacing the parent/container listitem with a card with collapsible cardtext improved performance tremendously. Maybe that will help someone.

+1. Small list(~10 items) with checkboxes is really slow.
