Can I get good performance by upgrading, or do I really need to reinstall?

Do you think I'll get better performance by reinstalling my NT Server instead of upgrading it to Win2000? Are there some specs or docs that explain it?

I believe that performance on a Windows 2000 Server is better if you reinstall the machine. The issues are primarily that the baggage of software that was installed on Windows NT gets migrated - which means that all of the issues and clutter that is with the application comes along for the ride. This is a general issue with machines (servers and workstations alike) unless some very strict maintenance rules are applied - which often in the industry they are not.

The other thing that happens is not necessarily system performance related, but operational performance related. If you put two machines side-by-side, one having been newly installed and one upgraded, you will find several difference in menu options and locations of files that can lead to issues in the future or when you are looking at other problems. For example if you install a new Windows 2000 Server, the user profile information is stored in the Document and Settings folder off of the root of the C-drive (or system drive). However, if you upgrade a machine, it leaves the WinntProfiles folder and profiles in tact. While this really doesn't matter to the machine, to a user trying to find -- say the All Users folder, this could get a little confusing. There are other items like this as well that are embedded in the operation of the machine and the registry.
