For my own interests, I would like to at least cover the following bases: 32 bit vs 64 bit vs 64 bit kernel + 32 bit user-space; data warehouse type tests (data >> memory); and web prefs test (active data RAM)
What specific benchmarks should be run, and what other things should be tested? Where should I go for assistance on tuning each database, evaluating the benchmark results, and re-tuning them?"
