I removed the showvariables and then did some timings and curve-fitting
on my machine. Gnuplot says that the function for Jacko's example is:
on my current (not so fast) machine. 200 equations take only 2sec,
but 1000 is 220sec and and 2500 would be 2969sec (almost 50min).
That is pretty awful performance :-(
