Jelly Bean RAM Hog

OK guys after spending two days with the new Samsung official software I was wondering if anyone else thinks that its a RAM hog. I have to keep killing the apps in the task manager otherwise I see lag while opening apps and things. Anyone else think this? Or could this possibly be because I quickly loaded about 40 apps onto the device? Any thoughts? Personally I hope Samsung will just improve and mature the software and it will get smoother. If not I might grab one of those deodexed ROMs.
