Yes, the Kanga had the 512k backside cache that was standard for the 750. I'm just pointing out to Bunsen that there were a few cacheless G3s (and that they generally suck).
The 601, and early 603 (not e), had some known performance issues with 68k emulation. There is some dispute over the severity, but running SpeedDoubler in System 7 was considered SOP back the day (substituting it for Apple's own 68k emulator).
In Mac OS 9, this is not possible, but I think Apple's emulation code had improved by then anyhow. Plus, most people had upgraded to PPC native apps.
Obviously, none of this seems to describe the OP's problem (a G3 can run 68k code faster than the fastest 68040), unless he's experiencing glacial speed with other 68k apps. In which case, that's interesting.
