This document discusses 10 ways to make Magento faster that do not directly involve changes to Magento. It recommends minimizing external service calls, caching static content close to customers using a CDN, reducing blocking operations like database queries over NFS mounts, and focusing on perceived page load speeds rather than raw stats. It also advocates testing performance changes with production-scale data loads.

What is more important?
How fast your site actually is
or how fast your customer thinks it is?

10. Keep content close to the customer
