Performance Optimization in Cilium.io

This outline covers the performance optimization techniques employed within the Cilium.io website.

Code Optimization:

• Cilium BBR: Cilium supports BBR (Bottleneck Bandwidth and Rate) congestion control, which is a Google-developed algorithm for boosting throughput by 50%. This is highlighted in the blog post “Accelerate network performance with Cilium BBR”.
• Cilium Bandwidth Manager: This feature provides rate-limiting per Pod, reducing latency by 4x compared to other solutions. It is designed for multi-queue and multi-core NICs, enhancing overall network performance. The blog post about “Bandwidth and Latency Optimization” in src/pages/use-cases/bandwidth-optimization.jsx provides details.
• BIG TCP: Cilium supports BIG TCP (Bigger TCP), which leverages IPv6’s Hop-by-Hop header to allow larger packets than the traditional 64KB limit. This improves performance in 100Gbps networks and is detailed in the “100Gbit/S Clusters With Cilium” section in src/pages/use-cases/bandwidth-optimization.jsx.

Image Optimization:

• ogImage: The ogImage property within several markdown files is used for image optimization. For instance, the post “Analyzing the CNI performance benchmark” uses ogImage: ogimage.png.

Caching:

Caching is not explicitly mentioned in the provided code. However, the concept is implied within the context of performance optimization.

Reducing HTTP Requests:

• Code Reuse: The provided code snippets demonstrate the use of code reuse for improving efficiency. For example, the src/pages/use-cases/bandwidth-optimization.jsx file reuses the sectionContent structure with different configurations.
• Modular Components: Utilizing components like sectionContent and heroContent promotes modularity, reducing code duplication and improving maintainability.

Note: This outline focuses on performance optimization techniques mentioned within the provided code snippets and Markdown files. Other potential techniques are not covered here.
