Memory usage problem in SSR when accessing getter

[jcfauchet]

Reproduction

https://github.com/xmimiex/vue3-ssr-template/tree/feat/pinia-reproduction-error
This simple exemple is accessing to a getter in SSR

# Home.vue
...
const environment = config.getEnvironment
...

Steps to reproduce the behavior

Follow the steps on the README

1. Clone the reproduction repository (branche: feat/pinia-reproduction-error)
2. install the project (yarn install)
3. build the project using (yarn build)
4. Start in node debug mode (yarn serve:prod-debug)
5. Run load testing command (ab -c 100 -n 1000 -k http://localhost:3000/)
6. Inspect the node debugger in your chrome browser

Expected behavior

Node memory should correctly regulate

Actual behavior

This getter seems to cause a memory leak.
For information, we also try a getter with parameter (without caching) and these one seems to not leak the memory.
If we remove this getter from Home.vue component, we can see the memory regulates as expected.

Hi,

As the store is re-create on each request on SSR, maybe a solution could be to not cache getters anymore on the server side ?
I just saw on the last Vue Release, a bugfix was added in this way

ssr: make computed inactive during ssr, fix memory leak (https://github.com/vuejs/core/blob/main/CHANGELOG.md)
