Hi Kris, Do you think you'd have a chance to load up Windows Server on the same machine and compare its MySQL and PostgreSQL to modern Linux, FreeBSD and Solaris? That's probably asking a lot, but I'm sure I'm not the only person interested in seeing how Windows' latest kernels perform for server roles. I just hope that, in such a benchmark, the userland software implementation is fair to the platform, and not degenerating to low-performance APIs from lack of optimisation. There's a lot of debate about the use of FreeBSD and Linux and others for servers, and personally I'm just happy to have so much choice available to optimise per project. But it'd be really great to know where Windows fits in the performance competition, and it's nice to have some numbers to point to when arguing that free operating systems outperform proprietary ones. -- Dmitri Nikulin Centre for Synchrotron Science Monash University Victoria 3800, Australia
