Which pack took more tech resources?

My game was starting to run slowly, so I first culled a lot of CC. Some of the things Z and I found soon after we bought the game aren't necessary now, because we've added packs, kits, etc. that include similar clothing and hairstyles. Getting rid of the excess CC made a noticeable difference. So did deleting old save files.

I hadn't thought of household inventories being a power drag, but once I cleaned out the inventory of our lead Sim's household, we got another boost. We're Simming on a decent laptop; it's far from a potato, but it's not a gaming rig either.
