Peter, this is a good idea with the Expand, and I tried it and I also see no slow downs. So I expect that it has to do with nesting of functions, so I try: Fold[If[r > 1/2, Plus[#1, #2], Divide[#1, #2]] &, x, Range[11]] which I then convert into a function: f[x_,r_]:=... This, then, has quite a few levels: Depth[f[x,r]] -> 25 Here I definitely can observe the editing lag, although still not as egregious as with my other work.
