Magento

I have a catalog of 9.000 products+ and a few K of attributes.

When I update 150 products at once, it will take 2 hours!

How can this be fasten up?

hi
get more ram, ssd storage, or just optimize mysql config.
this is obvious question,
update in smaller groups
2 hours sounds like you have some bad shared account

if you know your server limits there is nothing you can do above that

cheers

We have 10s thousands of products and 5s product save, you need better hosting, SSD is a bit over the top though.
