Auslogics is very fast.
The reason is, Auslogics Disk Defrag defaults to just "defrag", whereas Windows built-in defrag defragments and optimizes files which takes longer.
If you hit the drop down box in auslogics, you have several options, analyze, defrag, or defrag and optimize.
I don't find Auslogic's any faster than windows when using the optimize feature, but I still love it for XP and 2003 systems due to the scheduling abilities that are missing from those operating systems.
