Me and my friend are having the same issue. When I create a 1.7.4 server everything runs smoothly and good. When it's the new snapshot (any since 1.7.4) we get lag. Sometimes it gets to the point where the game is unplayable. The lag occurs on single player also. We think that it also might get worse when it starts to rain but we're not sure.
I am pretty sure my machine is capable of running MC with no performance related lag since it is powerful enough (it's Lenovo y500 with SLI). Moreover the difference between experiences playing 1.7.4 and the snapshot is clearly visible.
