Fictitious but reasonable demonstration of why: Two individuals A and B are arguing over the relative merits of their favorite systems OSA and OSB. Both are happy with what they have, but they agree to try the other and soon find that they were both right OSA is better for A and OSB is better for B. But they want to know which is *best* even though anyone with sense might stop at this point. Careful analysis reveals that OSA happens by default to be configured in a way that suits the hardware and workload that A has, but this configuration does not suit B's rather different setup and load as well os OSB does. Experts are called in to tune both OSA and OSB properly for each site. They test again. Lo and behold OSA is a clear winner, both settle on it. The argument is over ... or is it ? B gets some new hardware and calls in the same expert to tune up OSA for it. The performance is not what was hoped, just for fun he tries OSB - it flies better than was expected for OSA. A gets involved again, they realise that the two systems they originally tried had a major component in common (motherboard say) and the new box has a different one. They spend a fortune and buy every type of processor, motherboard, disc controller, disc drive, etc, etc. They set up a massive test with a fancy benchmark suite and test OSA and OSB across all this hardware variation and make a big graph (it only takes a decade or two but hey they *want* to know). They find that OSB wins on most setups and OSA wins on quite a lot, OSB is delcared the overall best. Settled ... or is it ? They publish their results in a million dollar report (got to pay for that hardware somehow), and as soon as it is published everyone in the industry criticises the benchmark as being totally unrealistic compared to real world use. Other point out that almost all the hardware they tested is now obsolete and the new stuff is very different. ----------------------------------------------------------- Yes, you really could go through all that and *not* answer the question. I have seen smaller scale insanity performed quite often, usually it sells magazines. However if you have a real job to be done and real hardware to do it in, then just try both and use the one you wind up liking best - or pick one and use it unless it barfs or irritates in which case try something else. -- Steve O'Hara-Smith <steve@sohara.org>
