power tuning is a set of techniques that manipulate the engine control unit (ECU) to boost the power output of a vehicle. These methods can be categorized as piggyback tunes, box tunes, or software-based tunes. Piggyback tunes are the most popular form of power tuning because they can be installed in minutes and do not void your factory warranty. They can increase performance, but will cause increased wear of your engine components and janky power delivery. Box tuners and software-based tunes can be used to increase power but do not affect your warranty.

PPM tuning analyzes the power configuration of a Lambda function and provides recommendations to optimize for cost and/or performance in a data-driven way. It is language agnostic so it can be used for any Lambda function in your account. To analyze a Lambda function, the state machine invokes it with multiple power configurations and then analyzes the execution logs to identify which power configuration maximizes cost or performance.

Navigating the World of Performance Tuning for Optimal Power

During the analysis, the CPU utilization is tracked to determine the best power management settings. The Balanced power plan focuses on power efficiency with a minimum of processor frequency and maximum utilization, while the High Performance power plan favors performance over energy efficiency at light to medium load levels. The analysis also includes response time sensitive workloads.

In addition to power optimization, the tool can be used to analyze and diagnose problems with your server system. One example is to find out if the server hardware can handle the power requirements of a given workload by using an application benchmark test to measure how quickly the CPU can respond.
