Re: Oracle performance under Windows 2000 vs. UNIX

Your question is quite generic, and it's not easy to provide a straight answer, but I'll try: I use Oracle on both platforms, and I certainly get more Oracle (9.0.2) error messages on Windows (2000 server pro SP 1) than on Unix (8.1.6 on AIX 4.3.3). I generally see better performance on Unix, but I don't compare oranges with oranges, since the Unix server has 2G of RAM, and Windows (on my laptop) has 256 MB. Oracle also has some differences in its implementation depending on the OS. For example, the Oracle processes are just that on Unix (you can see them if you issue a "ps -ef"), but they are just threads of 1 process on Windows. It's hard to talk about the base code without having access to it (it's not an "open" software, such as Linux for example), but my guess would be that the source code (written in C??) must be relatively similar from OS to OS, if we forget the optimization steps.
