I kept seeing people talking about how the XP orbs were lagging up their game, and didn't see it myself, playing SP.
However, I don't think think it is bogging the system down because of a buttload dropping on a player dying, but the orbs themselves.
I lagged up a bit during a load and didn't pick up a single XP orb; when I looked in it's direction I got a MASSIVE FPS drop. Look away, everything's fine. Seriously, just one XP orb was making my Minecraft go from about 30-40fps to 5.
