TCP Chimney offload is designed to free up CPU utilization and increase network throughput by moving TCP processing tasks to hardware. This frees up the server’s CPU for other tasks. This makes sense if consider the available processors, ram and types of tasks running. Chances are a VM is only performing a certain task and might even be network bound when considering how many VM’s are running on the host. If your VM has access to fast processors and enough RAM, you…
