You might have noticed after making the upgrade to AOL 7.0 that compared to AOL 34.0 it spends an inordinate amount of time grinding the hard drive any time you do any sort of activity in it, regardless of how fast your computer is. The AOLSpeed program improves this situation. What it does is patch an AOL program file (supersub.dll) to disable its unnecessary disk buffer flushing. The end result is an AOL that performs noticably faster on most operations and accesses the disk less (so it's quieter). Works on all AOL versons. You must be using the 32-bit version of AOL 4.0, 5.0, 6.0, or 7.0.
