Just "meet the minimum requirements" doesn't cut it anymore. Not if you have all EPs and are patched.
What have you tried, what steps? What guides have you followed? If not, the Freeze & Lag Intermittent Freezes FAQ (linked above) would get you started...

There's a reason they're called the minimum requirements not the "your computer will run this lightning fast" requirements. Have you tried dialing back the graphics options a bit? You might also want to see if Ellacharmed's fixed world for the world you're trying to use runs better.

Welcome to The Sims 3, quite possibly the most unoptimized game ever. Honestly even if you meet the requirements you should consider seriously upgrading your CPU and such if you're going to be spending any significant amount of time with this game.

Indeed, EA's "minimum requirements" are not "these are the minimum requirements to run the game playably well" but just "these are the minimum requirements to physically start the game - it may be completely unplayably poor at minimum specs."

i found this The Sims 3 Graphics Performance Guide interesting and useful for finding out which settings are worth keeping higher and which not. but if you only meet minimum requirement i have to agree with the others that playing the game will definitely become/stay laggy and graphic + gameplay settings should be low in general. (especially if your neighbourhood grows / relationships get established... data needs to be saved for growing saves )

there is also this guide: Game Help:Improving Sims 3 Performance
also i made good experiences with error trap and overwatch from nraas helping my game to run "better" BUT i dont think that it speeds the game up (i would say it felt like it slows it down even further)

also: having store items, expansion + stuff packs slows the game down. if you additionally use other CC then it make performance worse of course. thats why more experienced players went on and started merging their CC (packages only!) with s3pe or cc magic .
