Red Hat Enterprise Linux Network Performance Tuning GuideAuthors: Jamie Bainbridge and Jon Maxwell Reviewer: Noah DavidsEditors: Dayle Parker and Chris Negus03/25/2015 Tuning a Network interface card (NIC) for optimum throughput and latency is a complex process with many factors to factors include capabilities of the Network interface, driver features and options, the systemhardware that Red Hat Enterprise Linux is installed on, CPU-to-memory architecture, amount of CPU cores, the version of the Red Hat Enterprise Linux kernel which implies the driver version, not to mention the workload the Network interface has to handle, and which factors (speed or latency)
