Here, let me revisit this point. The test machine is a 1Ghz Pentium III Dell Inspiron 8000, with a 60Gb 7200rpm hard drive as the system drive and a 64Mb Nvidia Geforce4 440 Go running Arch Linux. (All calculations done via Timex method.)
Boot time from Grub to desktop: 27 seconds
Kazehakase start time: 2.54 seconds
Time to compile VICE 1.22 (make only, not configure): ~7 minutes 15 seconds
glxgears framerates: ~2175 fps
Boot time from Grub to desktop: 0:27
Kazehakase start time: 0:2.47
Time to compile VICE 1.22: ~7:08
glxgears framerates: ~2180 fps
Start times are identical. System loads are identical. Compile times are identical. Responsiveness, shutdowns and disk access are identical. Network access is identical. Even the color of the screen is identical.
Therefore, more memory will not always magically speed up your computer. QED.
