DNS Resolution and Performance

9 posts · Nov 2009 – Sep 2014

What this trail covers

Google's initiatives in DNS resolution and performance have evolved to include open-sourcing key technologies. Early efforts focused on providing a new public DNS resolver to improve internet speed and security for users. Subsequent developments have included the introduction and performance analysis of the SPDY protocol, particularly its impact on mobile networks, aiming to reduce latency and improve the performance of the web by enabling features like request prioritization, bidirectional streams, and header compression. This post details the use of compression techniques to improve web performance.
