I should add to this, as we know file system filters (e.g., anti-virus) slow down access to read (and write, but irrelevant here) files from any file system format on Windows (NTFS, FAT32, exFAT, etc), storing configuration data in configuration files would be less optimal, though minimal in terms of performance (given your app wasn't constantly re-reading the file). This wouldn't be the case with the Registry, as the hives are already open.
