It's all about the camber change as the wheel goes thru its travel. Setting up a double wishbone IRS takes time - there are quite a few 8-9 second IRS JZA80s in the USA. That said, there are plenty of very quick Datsun 1600s/240Z out there - I suppose after 30 years of development, it's possible to set up even a trailing arm IRS to be great.
I suspect that the theoretical/academic limitations of each setup only come into play in the upper echelons of motorsport. I remember reading that F1 cars have a total of 12-13mm suspension travel - hard to belive that such limited suspension travel could have a profound effect on a car's corner speed (given that there are so many other factors at play)!
