The graphs below represent a performance comparison between software programs designed to accelerate CD ROM performance. Test were performed on a Performa 6300. Testing was done using MacBench 3.0 . CD ROM tests MacBench profiles 5 popular CD ROM based software programs including Encarta Multimedia Encyclopedia, Myst and Passage to Vietnam and applies these profiles to the subsystem being tested. See this description of what MacBench tests and how.
Longer bars equals faster performance.
The optimal size of the acceleration file will vary depending on the CD ROM being accessed and the Mix score should be seen as just an example of how size can effect performance. The individual tests give you a more explicit picture of the caching process at work. During the first test the information is written to cache and during the second test the information is drawn from cache. Unexplained is the poor performance during sequential read of small bytes of data which was not true during random read of the same sample size. As always it is a good idea to get multiple perspectives when considering a purchase.
