Measuring and improving performance is particularly important for eBay and its family of companies. When 100% of traffic carries e-commerce, every millisecond counts. eBay’s Site Speed Team leaders from Network and Platform engineering will give a detailed walkthrough of eBay’s methods for continuously measuring and improving site, transaction, and API speed across devices and geographies.

This technical session will cover aspects throughout eBay’s performance engineering, and highlight:

- CDN strategy with before/after metrics from global CDN architecture changes

- Best Practices and examples of eBay’s use of synthetic testing

- Deployment failures and what we learned from them

- Specific descriptions of code related changes that worked- from FEO to replatforming

- eBay’s implementation of NAVtiming for RUM

- Examples of improving web and mobile-app performance

- Goals and vision for the future along with ideas for the Velocity community

Key takeaways for the audience will include specific examples of how to use the same tools, used by eBay and PayPal, to impact their own environments.
