Quickly remove contents from NSArrayController

HI. I have an NSArrayController which has over 15000 entries. When I clear the array using

[itemBrowserArrayCTRL removeObjects:[itemBrowserArrayCTRL arrangedObjects]];

it takes a long time... like 10+ seconds on my MacBook Pro.

Is there a quicker way of clearing the contents ?
