I occasionally post about issues I'm having with my game but my issues are caused by my play style. I have extremely overstuffed households (20+ Sims in a household) plus all Expansion and Stuff packs plus all store content plus about 4 GB of mods and custom content.
One thing that helps greatly is to keep inventories as empty as possible. Sims can collect a lot of stuff during game play and after a few play sessions it is a good idea to go through their inventories and remove what they don't need to carry around with them all the time.
