What about Windows/Linux vs. AIX and Solaris..?

For me, though, one of the biggest considerations would be to evaluate where your system admin's skills are. If your organization has equal skills in both windows and linux, then I guess this factor won't matter much. However, if you're in a windows shop with no command-line OSes in the data center, then you may not be well-equipped to install, configure, and, perhaps most importantly of all, tune a linux system. Same argument can be made swapping the OSes as well. Just a thought--the "best" platform for your environment will often be the one that you know how to run the best.

Executive summary - there's nothing in it worth worrying about. There's a 64 bit comparison out there as well. Executive summary - there's nothing in it worth worrying about. The consistent, but small difference is that Windows tends to do IO intensive loads better, Linux CPU/Memory intensive loads better. None of this is on my new site and I need to change that so thanks for the reminder. Ease of use and support match very well with the skill set of your existing employees - boths dbas and sys admins. Linux is of course free to download and test, and handily so is windows for 6 months. You should be able to do the tests yourself. Swingbench from dominicgiles.com is a handy free oracle centric tool.
