File System Performance

Three types of tests:

• operations that hit disk cache: NetBSD the best performer. Windows 32-bit file system the best of the Windows versions. NT three times worse than NetBSD.

• access to small files that go to disk: NetBSD the best performer. Windows NT twice as bad as NetBSD.

• file creation: NetBSD is much worse (by a factor of 3-5), but it uses two disk writes to guarantee integrity of file system across system failures. Just cached in FAT file system of NT.
