Folks, FWIW, the applications where I did direct 32 / 64 comparison were a) several data warehouse tests, with databases > 100GB b) computation-heavy applications (such as a complex calendaring app) And, as others have pointed out, I wasn't comparing generics; I was comparing Athalon/Xeon to Opteron. So it's quite possible that the improvements had nothing to do with going 64-bit and were because of other architecture improvements. In which case, why was 64-bit such a big deal? -- Josh Berkus PostgreSQL @ Sun San Francisco
