There are several reasons why performance for a clean installation will tend
to be superior to that for upgraded systems.
An upgraded system will constrain the placement of files and file system data.
The old disk format may not use an optimal file system cluster size. In a clean
installation, the placement of file system data on the disk and the internal
organization of that data can be optimized, resulting in a smaller system
footprint and fewer and faster I/Os when using the system.
When performing a clean install, Microsoft recommends that NTFS be used
and that the system be installed in a single partition on each disk. Under
Windows XP, big partitions are better managed than in previous versions
of Windows. Forcing installed software into several partitions on the disk
necessitates longer seeks when running the system and software.
