Time for my fly story again. It goes something like this.

This scientist experiments with a fly. Places the fly on the table. Claps his hands close to the fly. The fly flies away. He then break the wings off of the fly and claps his hands again. The fly does not fly away. So he records on his clipboard that a fly without wings is deaf.

Moral of the story. If you do not know that wings is what causes a fly to fly, thinking that a wingless fly is deaf seems to be a vaid conclusion. Despite the fact that it is very far from the truth.

The reason for the one machine to be slow could be anything from an incorrectly configured half-duplex network card, to having the infamous 3D OpenGL Pipes screen saver running and consuming most of the resources of that machine.

Observation alone means *nothing*. No valid conclusions can be made for observation alone. Especially not when dealing with performance comparisons which by their very nature is a an extremely complex beast.

IMO you have not proved or shown anything that Linux is indeed a faster o/s than Windows for Oracle performance.

Performance is not the choice that is made when deciding on o/s. The real issues are support, maintenance, usablity, flexibility, scalability, levels of support for external devices (e.g. SANs, robot tape drives), in-house compotence in support and administrating it and wheher or not that o/s will run properly on the h/w range that is considered to be use. (btw, I have seen many times that the h/w decision is the primary one and not what the o/s is).
