Summary

Domain sharding, a technique where webpage resources are split across different domains or subdomains, is generally considered beneficial as it allows more connections and faster downloads. However, with the adoption of Google's SPDY protocol, domain sharding can actually hinder performance and is not recommended. This is because SPDY enables multiple resources to be fetched in parallel over a single connection, making domain sharding unnecessary. Instead, using a certificate that covers all domains involved can result in better performance for both older browsers and those supporting SPDY. CloudFlare offers simple SSL options and push-button SPDY activation, facilitating this approach.
