I knew I read this somewhere, now I found a reference ;)

ZWF's Atari STE fanpage has Paranoid's excellent STE programmer's documents, and on page 6 I found the following:

? How fast is the Mega STE at 16 MHz without the cache ?  ! Unfortunately, not very much faster than an ordinary 8 MHz STE. The cache might seem small according to todays standard (16 KBytes), but for a system like the Mega STE, it reduces memory accesses dramatically. If you turn off the cache, the 68000 has to fetch everything directly over the 8 MHz bus. Only operations that completely work in the 68000's registers will gain performance.

So if you don't have bus write cycles during the blitter execution, then I guess you can use the cache like that :)
