Yeah, this is a pretty old post.. Domain sharding, which is how resource rich sites enhance parallel loading, doesn't suit SPDY at all.

- bluesmoon 14y agodomain sharding has been unnecessary since 2011 when browsers increased the number of parallel connections they make to a single domain. With these increased connections, domain sharding might end up hurting performance if all shards point to the same IP address. This is so because many home wireless routers and DSL modems start dropping packets if too many SYNs go out to a single IP without an ACK coming back -- they think the client is mounting a DoS attack and try to block it.
