Optimizing Energy Efficiency On Red Hat Enterprise Linux
Red Hat, Friday, October 17th, 2025
The energy efficiency of data centers and high-performance systems is becoming increasingly important. Energy costs can make up a substantial portion of the operating expenditure (OPEX) budget, potentially serving as a critical factor in the success or failure of a business.
This article breaks down the issue of energy efficiency in modern server platforms, presenting tools and an example methodology for measuring power consumption and performance. As a case study, we present measurement results from two server platforms with different CPU architectures. We will emphasize network performance (including throughput measurements), CPU utilization, and power consumption, with a particular emphasis on achieving the highest possible throughput per watt of energy consumed.
