I used process monitor and found a bad package and removed that but it didn't totally eliminate the lag. I could always add another rural school if I need to do so.

So far, all rabbitholes look good although I don't have any kids in the hood so not sure about the school. The lots all looked good though and the roads were drivable without issues at all. There may be some isolated patches but nothing that I could find. The town is pretty spread out except for one small area that is more like a downtown but no huge lots or skyscrapers. I check my routing pretty carefully so no overlapping roads, no kinks or roads without intersections. If the jerking stops after you reset, then it's a routing problem. You can check whether routing is the cause of your problems by using the cheat 'resetsim *' to reset all sims you can also use Twallan's master controller if you have that to do the same thing. Schools and busy rabbitholes- you can have more than one of each, so if you have more than say 10 kids, you may want two schools! Rabbitholes can be quite a bottleneck. Inaccesible areas or bottleneck paths- make sure you have more than one route to get to busy areas- so if you have a single path to a rabbithole, place another path too! Overlapped roads- it's easy to place a road over another without realising

Roads without intersections- if you have a 'dead end' road you must have an intersection to finish it Mark these 'No Visitors' so that the whole neighbourhood isn't trying to get to them autonomously! Unroutable lots (for example, lots accessible only by dive wells or subway, or perhaps hidden under a geodome). Tiny missed patches in your 'sims non-routable' paint (sims can get stuck in silly places, especially when they return from vacation) This choppy gameplay is usually down to routing, as the game will try to recalculate a route and, when it fails, will recalculate over and over.
