  • Not a current way to do this. This plugin focuses on HTTP/2 in which case domain sharding can actually hurt your performance.

    Domain sharding technique was used to maximize the amount of parallel TCP connections. But due to HTTP/2 multiplexing this performance optimization doesn’t make sense anymore. It actually might decrease performance on a HTTP/2 connection, because the browser has to perform additional DNS requests and manage more TCP connections.

    Thanks for the reply, Brian,

    The option woud be nice as currently no browser supports HTTP/2 unencrypted and not all websites are being served over SSL. There’s also still a lot of people lunking around on antiquated browsers for which sharding is inherently effective.

    Lastly, there are indeed scenarios/dynamics in which sharding over HTTP/2 is effective if implemented correctly; which is why, as one example, and at least in part, the rewrite_domains PageSpeed filter still exists.

    Be well,
    AJ
