One big DB or two not-too-big DBs? FKs across DBs are slower?

i know there's several threads around, but none of them answer this question:

in terms of performance, is it better have two? or one?

note: even in the 2-db-way, it would be FK's between tables, so, another question would be:

FKs across databases (db1.table1 has a FK of db2.table1) are slower than the ones within a single database?

thanks
