Dimension Data provides 9x bandwidth throughput

Note: Neither IBM nor Rackspace offers a 1 vCPU solution. For this test, the Rackspace “small” machine has 2vCPUs and 2GB RAM. All tests run with a “large” system

as a partner across low-latency, internal network. Throughput can exceed GbE because of 10GbE back-end trunking. IBM running RHEL 6.3, all others running Ubuntu
