The graph shows Puran Defrag 4 (PD4) in dark blue, and the results from Windows XP in light blue. The first test is at the bottom, and shorter lines mean faster times.
- "Basic XP" refers to the standard install, without Office 2007, so there are only 710 files to be tested.
- "Defrag" refers to the read times of the same 710 files, after two defrag passes using the full PD4 boot time defrag, with no "Optimize Files" or "Optimize Boot" options enabled. A 17.3% performance improvement is measured.
- "Defrag+Auto" refers to the read time after enabling both the "Optimize Boot" function in Windows, and then allowing Windows to optimise the placement of system files. After this a further boot time defrag is done, with no additional options. An improvement of 32.6% is recorded, 8.1% faster than WDD.
- "XP+Auto" is the result obtained after enabling both "Optimize Files" and "Optimize Boot" functions in Windows, and then running WDD, i.e. the best that Windows XP can manage.
- "Basic Office" refers to the read time of all 802 test files, where no defragmentation has been done whatsoever, after the installation of Microsoft Office 2007 Professional (Trial).
- "Full Defrag" refers to the read times of the same 802 files, after a full boot time defrag with all options enabled, with no "Optimize Files" or "Optimize Boot" options enabled. A 27.6% performance improvement is measured, as good as the Office Auto result below..
- "Full Defrag+Auto" refers to the read time after enabling both the "Optimize Boot" function in Windows, and then allowing Windows to move the system files around. After that a simple boot time defrag, with no additional options, was run. An improvement of 32.3% is recorded, 6.2% faster than WDD.
- "Office Auto" is the result obtained by allowing Windows XP to do its own defrag after enabling both "Optimize Files" and "Optimize Boot" functions.
An average 27.4% performance improvement over no defrag at all is excellent for a $24.95/$14.95 (special offer) commercial package, beating all the other "heavy hitter" commercial programs tested so far. In most cases it works as well as or better than the built-in windows defrag. It also has an optional automatic defrag that is really not intrusive at all, and some other useful features. The only thing "missing" is a file placement display. The picture at the top of this article is a composite of two "Analyse" screen shots, one taken after installing Office 2007, and the other taken after the final test, effectively showing before and after situations.
The next test candidate is UltraDefrag 1.2.3
