valtio's proxy is 10~30x slower than @vue/reactivity

big Object, proxy 10000 tims;

why valtio's perf is slower so much? seems like both those two libs just warp a Proxy , same way

Currently, valtio's proxy(initialObject) copies the initialObject deeply to keep initialObject isolated.
So, you don't need to do Object.assign({}, ...).

In v2, we will be changing this behavior. #703

[jiangjiu]

sounds great! and when will the stable version V2 be released? about serveral months?

[dai-shi]

As written in #703, we are waiting for the RFC to be finalized. Then, v2-alpha, after a while v2-beta, then v2-final, I guess.

I'm not sure if v2 will improve performance or make it worse. We'll see.
