FastExpPickup

Configure the experience orbs pickup speed

-completely serverside-

pickup delay: sets the time in ticks between two possible orb pickups

orb per pickup tick: once the player can pick up orbs again, make experience gain even faster by picking up multiple orbs per tick; max amount set here

more game versions to come on interest

but I would just use the Clumps mod for better performance once its out for the newer Versions
