This also seems to be an issues in 15.04. The system monitor appears to double network throughput when using a VPN (likely because its adding the VPN interface throughput to the underlying wlan/eth interface throughput, effectively double counting it). Confirmed with OpenVPN (via Network Manager plugin) on Ubuntu 15.04.
