We have tested the patched kernel on one network intensive (high packet) workload with max_cstate=1 and ondemand governor disabled and it has lower network throughput than the default kernel had with intel_pstate=enable. There also appears to be a futex performance issue with the c4.8xlarge which we are still investigating and may be contributing to the problem.
