Yeah, with 30mm rims I would definitely want to try a 2.5.
As far as blasting through rough stuff faster? Maybe, or maybe not. Look at what Enduro and DH racers are running, and you see mostly 2.3 through 2.5. So some are finding 2.3 faster, some 2.5. There are a lot of factors going into what works best. You probably won't really know unless you try it.
