## AI overview

This article explains how Kubernetes CPU limits and throttling can affect the performance of Go services. It examines millicore-based CPU settings, including a 250m limit, and discusses why services may run less efficiently when they are not configured for the assigned CPU scope.

## Source excerpt

Kubernetes CPU limits can look straightforward on the surface, but their impact on application performance is anything but simple. This article unpacks how Go services interact with Kubernetes CPU throttling and why a seemingly harmless configuration such as setting a limit of 250m can dramatically constrain performance in production. First published in February 2024, its insights remain just as relevant today for anyone running Go applications in containerized environments and for developers who want to avoid costly slowdowns.
