Smalltalk/V (not 286) was perfectly usable on a PC of the day, I ran it on an Olivetti M24 with a paper white display.
The Smalltalk-80 flyer states that an 8MHz 286 was faster than a Xerox Dolphin and 20% of the speed of a Xerox Dorado. The painful part would have been the display, they were just using EGA (640x350) so you couldn't see much at one time. I saw a demo of this and don't remember thinking that it was too slow.
