I think today "publish more papers" is bad career advice for young people. Better to publish fewer and better work
Most good institutions, both employers and funders, have stopped counting papers. What's more, often in applications you are asked for "your 3 most important works". If you salami-sliced your work into thin papers then your 3 best papers will look anemic. No quantity of papers can save you
The only institutions that still count papers are fhe ones you don't want to end up anyway. Clearly their management consists of nitwits who will make your life miserable
