I pitted the oldest version of Defraggler (1.0.31 Beta) against the newest version (1.20.201).
I have a P4 dual core 3.2 GHZ machine with a 7,200 RPM harddisk & 2 GB mem.
I timed how long it took the first iteration of Defraggler to analyze the drive, & it was 25 seconds for the first analyze.
The latest version of Defraggler, by contrast, took 3 seconds or less to analyze the drive.
Using MS Calc, I was able to divide 25 seconds by 3 to arrive at the realization that 1.0.31 Beta was 8.33 times slower (at least) than 1.20.201 in analyzing. I can only assume that it is likewise with other operations.
Conclusion... The latest absolutely TROUNCES the earliest!
