Magento 2 Slow import when 900 attribute options

We have a store with 35000 sku and there are 950 attribute options –

We find that when making any updates to products like price or qty or any other changes it is very very slow – like 5 mins if saving via Admin

We have tried some import/export extension like Firebear but these also seem to be slow

Came across this patch by Magento –
MDVA-31021: slow import and export

1. Has anyone tried this and does it make any difference? with import speeds

With Native Magento Import or With other Import Extensions?

2. Has anyone tried it with Magento 2.4.3 Adobe Commerce (all deployment methods) 2.3.0 – 2.4.1
