For any reasonable RDBMS deployment resources PostgreSQL has been faster than MySQL for me. Write-heavy loads are a huge win for it, but even on large reads (formerly its weakness) PostgreSQL has the advantage unless you've got no writes at all on the table. I guess if you've got completely static data MVCC isn't a win, but at that point I'm not sure you need to be using an RDBMS in the first place...
