I've got a quick question about character wealth/treasure.

I have a party of 4 PCs at level 6 (just hit 6 last session), and the treasure table says they should have about 2k gp total value. Is that per PC, or for the whole party? Right now they've got about 1k gp each in total value, between having gold, 1-3 upgraded weapons each (depending on class), a few magic items of various levels, and plenty of potions and what-have-you. Am I showering them in loot, or way behind?
