For computational stuff in my experience (Image analysis software using Feedback networks with a mix of floating and fixed point work) there was not much to choose between the various OS's because the limiting factor tends to simply be the hardware calculating throughput. If you have networking or IO as part of the equation then of course it's different. One deal that we can offer you that Linux won't is that if you are prepared to work with us, we can help you find any bottlenecks that are hitting you..
