Performance Boost From Using SpeedDoubler and RamDoubler Together

The graphs below show the performance boost on a Performa 6300 when using RamDoubler and SpeedDoubler together. A 512K Disk Cache was set for testing. Testing was done using MacBench 3.0. MacBench profiles popular software programs such as Adobe Photoshop, Word 6.0 and QuarkXpress among a variety of others and applies these profiles to the various subsystems being tested. See this description of what MacBench tests and how. Longer bars equals faster performance.

Disk Mix Comparisons

Comparison Graph

The graph below represents a performance comparison between using RamDoubler and SpeedDoubler and using Virtual Memory and SpeedDoubler. On this machine with 16MB of RAM RamDoubler will give you a total of 32MB. Virtual Memory for this test was set to 34MB giving a total of 50MB of usable RAM space. Tests show only a very slight slow down in speed when using Virtual Memory. Virtual Memory takes up the equivalent amout of disk space as toal memory (ie 16MB + 34MB in this case) and this space is not available for other purposes.
