Benchmarks*: Auslogics Disk Defrag 1.4.10.249

The review of an earlier version of Auslogics Disk Defrag is here, and I have uploaded the results of the benchmark tests in a spreadsheet. A quick summary of the results is simple: it doesn't work as well as the Windows Disk Defragmenter (WDD), which is supplied with Windows XP. Since this program is also freeware, the only thing going for it is that the interface is friendly and the results are shown in a graph. That's about it.
The graph shows Auslogics Disk Defrag (ADD) 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 several defrag passes using the ADD program, with no "Optimize Files" or "Optimize Boot" options enabled. Only 8.2% performance improvement is measured.
  
• "Defrag+Auto" refers to the read time after enabling both "Optimize Files" and "Optimize Boot" functions in Windows. Think of it as ADD with help from Windows. An improvement of 11.5% is recorded.
  
• "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 time of all 802 test files after several reboots and several passes using the ADD program, with no "Optimize Files" or "Optimize Boot" options enabled. A 16.8% performance improvement has been measured.
• "Full Defrag+Auto" is the result obtained after enabling both "Optimize Files" and "Optimize Boot" functions in Windows, and then running ADD. This improved the performance to 23.3%
  
• "Office Auto" is the result obtained by allowing Windows XP to do its own defrag after enabling both "Optimize Files" and "Optimize Boot" functions.

The performance improvement ranges between 8% and 23%, with better results obtained when the built-in Windows functions are employed, using Disk Idle Optimiser to enable them. The results are not as good as WDD, but fewer defrag passes are required, and the defrag program works nicely. Still, a 15% performance improvement isn't bad.
I look forward to see how Diskeeper 2007 performs. The testing has begun.
