Performance:
Performance tuning in PostgreSQL mostly involves modifying postgresql.conf file and updating the memory related parameters according to your needs. This information is available in official documentation as well as google 'PostgreSQL performance' will also return several useful articles. Of course, you can always utilize EnterpriseDB Tuning Wizard to fine tune your PostgreSQL installation.
Benchmarking:
You can use BenchmarkSQL to benchmark PostgreSQL. Find out about it at http://pgfoundry.org/projects/benchmarksql/
Post your comments if you require more detailed resources/links.
