[Kernel-packages] [Bug 1477171] Re: Enable intel_pstate by default on Trusty EC2 AMIs
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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1477171 Title: Enable intel_pstate by default on Trusty EC2 AMIs Status in linux package in Ubuntu: In Progress Bug description: Please can the intel_pstate driver be enabled by default on the Ubuntu EC2 AMIs.
