Pinia makes the whole app very slow

[digi604]

So we have a very big and complicated order management app with 7 different stores and price recalculations on IE11 take up to 30s compared 200ms on iOS. When we removed pinia as a store and used Vue.observable() instead it went down to 30ms on IE11 and very fast on iOS

This is partially related to the cost of using the composition api.

Without any code, any further analysis of the perf bottleneck, I cannot even give you a hint 😉
This is likely to also be related to the actual code you are writing

If you find more information about what’s causing the perf issues and can provide a boiled down reproduction, I can take a look
