I assume that, for complex queries, you have all the appropriate indices etc. Also, I have to admit, that for single-client scenarios and simple, mostly read-only queries, PostgreSQL tends to be slower than Access and MySQL. However, this changes as soon as you have multiple concurrent writing clients. You should take this into account when benchmarking your servers (by modelling the appropriate benchmarks), and when deciding which database to use (by trying to estimate future usage patterns).
