True, a customer must buy if the application is waiting. But it is also true that any set of benchmarks more than 3-4 months old are likely to be obsolete. Taking the last 6 months, in fact, Oracle issued one new release, and Ingres 2. Each of these releases increased "overall performance" by 25-40% or so (depending on who you are talking to and which core functions you're looking at) - and both vendors promise more of the same in the near future. When looking at performance, one aspect that might be worth investigating is how each competing vendor achieves that performance (the "uderlying technology"). This may give a clue to what the vendor may be able to achieve in the future re further performance enhancements. While perform- ance of some RDBMS's is now decent, some areas still leave much to be desired- for instance, obtaining aggregates (especially "a by b") is still quite painful, time-wise, in most systems. greg pavlov, fstrf, amherst, ny.
