What network card are you using on the director? There's only so many interrupts you can generate from one NIC before the CPU wedges - and in most cases every packet generates in interrupt. If you're using plain-old-PCI, you get less throughput than more advanced PCI variants. There was a thread about this recently. Search the archives for it.
