I tried disabling iptables and rebooting and have confirmed that all iptables modules have been removed from the system. The performance improved a little - VPS <=> VPS got up to 545.68 Mbit/s - but not much.

The networking is default. These nodes are two of an 8 node cluster. Each node contains a dual port ethernet card, of which one port is in use. According to lspci, we've got a Broadcom NetXtreme BCM5721 Gigabit Ethernet PCI Express (rev 11). Each machine has 2 GB of memory. The CPUs are dual core AMD Opteron 175.

Let me know if you need anything further.
