The most important parameter is probably your network: 1GbE or 10GbE? For 1GbE, as a rule-of-thumb, fully-virtualized can't fill the pipe, para-virtualized can fill the pipe but has a much higher CPU utilization than native, and passthrough is pretty close to native in all parameters, assuming a direct-mapping strategy.
