Wow, 2000 would be a challenge. I think they are at something like 600 movements daily at present. It is tough (or impossible) to get the separations as in RL. If I can get a departure in position on 27, I can get him off with an arrival about 3 miles--controllers seem to regularly take off and land with only 2 miles between them. What would help this sim a lot would be keeping the arriving a/c on a quicker roll out pace. They tend to slow down too much after touching down.
I have seen the strange pushbacks from cargo, too. I do not run runway 9 too much but have seen pushback anomalies where a/c that get pushed out onto Bravo act like they are headed for 27 and then have to swing around for 9. Not too big a deal but eats up some time.
Finally, have you seen the a/c do the pirouette off of 27? Right after TO, many a/c do this at about 500 ft AGL. Pretty funny and I will have to try and capture with a screen shot.
