The size of postgresql database was ~74GB for every test combination. The bare metal server had 256GB RAM for every test combination.
The only difference was the amount of RAM PostgreSQL could use - as specified in postgresql.conf.
So, 74GB database does not fit in PostgreSQL cache for 32GB instance and fits for 200GB instance.
