Just an anecdatum: I used lpsolve, a general linear programming solver, to layout constraint based user interfaces with no perceptible delay to the user in a desktop situation (no network to blame)… in 1996, on an Intel 486dx50 with 16MB of RAM. I think my cell phone with 80 times the RAM and 40 times the CPU speed can probably swing it too.
