Admittedly since I haven't played against other humans my experience has been limited. As for mass building, I usually do have several teams of engineers building masses of energy plants/mass fabs, several weapons factories etc. I think I had begun to tire when I started building an 'Ace' sub (nuclear sub), realised I had washing to do at my girlfriends house, and so cycled round, did the washing up, came back 20 minutes later and despite having a small army of engineers on it, it still hadn't finished! By the by..do T3 engineers build quicker?
What might be happening is that your pc is slowing down as it cant handle all the units in play. Then you end up with 30 mins on the in-game clock actually taking an hour, say. That happens sometimes - are you on a dual core?
Yes, T2 engineers build faster than T1, and T3 are faster still. Best of all is upgraded support commanders. Realistically, to get them done in a reasonable time you want at least 10 T3 engineers working on any one project, with all the mass and energy they need to work to full effect. For big things like nukes go for 15, and it should be done in a couple of minutes.
In my game yesterday I think those 4 Monkeylords took about 5 minutes to complete.
