HugeTreeMenu render relay

[yesvods]

I got a render delay of more than 150ms when I checked a tree node of tree up to 200 nodes.
Is there any example for huge tree menu?

I've used react perf tool to measure performance problem.It seems that ProxyClass>ProxyClass is the problem.
As I only change a property of tree object,why ProxyClass cause so much performance problem?

I've the used component w/ large trees before w/ no problems. I am thinking this is an external issue. Can you provide a gist or something I can look at?

Sure, I've create a gist.https://gist.github.com/yesvods/d8e8c4deb59a78407457
The dataCal time cost less than 3ms while rerender cost much of time.

There's a lot of other stuff going on in that render method - I'm not convinced this is related to the TreeMenu component.. have you tried isolating the TreeMenu component in the render method to see what the performance characteristics are?

Hello @MandarinConLaBarba , I've removed other stuff.But rerender still cost more than 150ms.And I can't find what's the performance problem with TreeMenu
