We measured both boot and shutdown times with a stopwatch, before and after loading each suite. We measured system performance using Ziff Davis's Business Winstone 99 benchmark tests. We ran Winstone on the system before and after installing the suite, and we report the results as percentage of performance lost. Bold type denotes first place. Low scores are best.
High scores are best.
We tested using 27 bugs. Our Registry Cleaning and Optimization test compares the performance of the suite's Registry cleaner against Windows 98's own built-in Scanreg utility. The scores represent the percentage of reduction in the size of the Registry. Interestingly, Windows' own Scanreg outperformed all of the suites. To evaluate Crash Protection, we used synthetic and application crashes.
