Also, I don't think performance on Windows is as good as on Linux/*BSD yet. Against switching OS is the fact that you presumably don't have the skills in-house for it, and the hardware was chosen for Windows compatibility/performance. Speaking of which, what sort of hardware are we talking about? -- Richard Huxton Archonet Ltd
