Not by using just Workbench. Or at least, not at the default 4 color scheme.
With just 4 colors, only half the DMA bandwidth is used. The 68k can only use half the DMA too, so effectively they're using half each and not disturbing each other.
FAST helps a great deal when really using the chipset (16color hires/lores EBH/HAM6 + sprites + sound playing + floppy access + blitter running), or with a faster CPU, which is why accel boards usually bundle some FAST in them.
e.g. when I did word processing with Prowrite or Kindwords, I'd leave the screen in 4 color mode, because modes with more colors made the word processor less responsive (higher latency). With FAST, you're immune to that. Of course, unless you fill the whole FAST and the system starts handing out chip instead.
