Hello Daniel I think your conclusions about the timings of Map and Do are not correct, because you use the function "fun" with Map and the undefined function "f" with Do. If I use the function "fun" in all three cases I get roughly (note: even though I restart the Kernel each time I get slightly different results with every evaluation) the following times: {1.1, 1.3, 1.5}. If I define "fun" as x^2 I get the following times: {1.1, 3.6, 3.6}. Therefore I conclude that using Map has advantages over the Do construct. Best regards Norbert Marxer www.mec.li
