CPU & RAM by Chunk?

[IceNine]

Are there any mods or server utilities for tracking CPU and RAM used in each chunk? I would like to be able to track down a leaky pipe or other more minor performance problems by location without having to visit every house on the map.

I know tekkitrestrict plugin has a command "/tpic" where you specify a number and it'll teleport you to a chunk that has that many items in it
