Previous benchmarks tout great benefits, ranging from making pages load 2x faster to making mobile sites 23% faster using SPDY and HTTPS than over clear HTTP. However, when testing real world sites I did not see any such gains. In fact, my tests showed SPDY is only marginally faster than HTTPS and is slower than HTTP."
