Update: here is a document explaining why HTTPS is faster than HTTP.

It boils down to a Google-developed additional session layer (SPDY) from which only HTTPS profits. Basically it is not HTTPS vs. HTTP but multiplexed sessions over a single TCP connection versus unmultiplexed sessions. It would be possible to do HTTP over SPDY too (it is just not done). HTTP2 is basically SPDY standardised and further developed.

In principle HTTP is slightly faster than HTTPS: there are caching facilities so that not every retransmission has to be originated by the client. HTTPS lacks that because relaying stations cannot read what they transmit.

How SPDY speeds up things is especially via the session multiplexing. This gains lots of time because of the delayed TCP-ack, which takes 500ms.

NAME
xflip, meltdown - astonish your friends with interesting X effects SYNOPSIS
xflip [-planes] [-vert] [-oblic] [-fast | -random] [-times number] [-display displayname] meltdown [-planes] [-display displayname] [-delay x] [-wait n | -wait 0] DESCRIPTION
This manual page documents briefly the xflip, and meltdown commands. This manual page was written for the Debian GNU/Linux distribution (but may be used by others), because the original program does not have a manual page. The programs play with the X display, producing some interesting effects. One traditional use of these commands is to have them run and affect someone else's X display, as a practical joke. OPTIONS
-display displayname The X display to operate on. -planes Operate on a singleplane at a time. -vert Flip the screen vertically. -oblic Flip the screen vertically and horizontally at the same time. -random Flip small random peices of the screen instead of the while display. -times number Specifies the number of peices of the screen to flip when -random is used. Default is 300. -delay x Meltdown may run too fast on fast computers to be fully appreciated; this can be used to slow it down. If specified, every x times the display is updated, a 1 microsecond delay will be inserted. The default is no delay at all. Reasonable values for x are in the 20 to 200 range. -wait n Makes meltdown wait for n seconds after the screen is totally black. If you pass 0 to -wait, it will wait until you press a key or mouse button. AUTHOR
