Ah, sure. Especially the bit about the cache :) Though I usually find
that download times on https vs http aren't all that different; it
takes a little bit longer to establish the connection, but less than
the variation in DNS timing. Most of the time, the cost of encryption
isn't the bottleneck - on a large download, transfer throughput is
usually what takes the time, and on a small download, it's too hard to
measure the cost anyway.
