Great Bridge, the company formed to support Postgres (the open source relational database), has released benchmarks showing that Postgres outperforms MySQL and Interbase by a wide margin, and keeps up with two unnamed proprietary relational databases. (We can all hope that they’re SQL Server and Oracle 8i.) The proprietary databases remain unnamed due to restrictive licensing agreements that disallow publishing of benchmark statistics. (These benchmarks, like all benchmarks, should be taken with a grain of salt.)
