Adam Jackson 137ac094e7 dix: Push UpdateCurrentTimeIf down out of the main loop 
This was added in:

    commit 312910b4e3
    Author: Chase Douglas <chase.douglas@canonical.com>
    Date:   Wed Apr 18 11:15:40 2012 -0700

        Update currentTime in dispatch loop

Unfortunately this is equivalent to calling GetTimeInMillis() once per
request. In the absolute best case (as on Linux) you're only hitting the
vDSO; on other platforms that's a syscall. Either way it puts a pretty
hard ceiling on request throughput.

Instead, push the call down to the requests that need it; basically,
grab processing and event generation.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:
http://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the
Xorg mailing list:

        http://lists.freedesktop.org/mailman/listinfo/xorg

Please submit bug reports to the Xorg bugzilla:
