The following results are the results obtained by a speed test program by
Floyd Zink author of BLU.  4 programs were tested 20 times each and the 
results averaged.  Writting on a IIgs to 3.5 disk.

Tested were AE cache program, Deviersi-cache, and Glen Bredons Cache and Cache
XL from Prosel.  The program does 50 writes and 100 reads and will be posted
shortly on apple2-l.

Avg	non	AE-Cache	Diversi-cache	Prosel-cache	prosel-cachexl
First   24.2	34.4		   34.4		   24.1		   24.1
subsequent 	11.3		   11.6		   24.1		   24.1

As is noted both AE-cache and Diversi cache took longer on the first access
than on subsequent runs.  AE-cache was marginally faster but as it must be
installed after booting where as Diversi-cache can be added to your prodos8
or 16 program thus speeding up the boot process significantly.  Further testing
is required to see the results on large file loads and writes to see the 
effect.
