Xlib is all about low-level tasks, and very intentionally leaves
high-level tasks to the various toolkits. In order to get much lower
level than Xlib, you'd have to use write() directly on the socket...

Seven seconds! The last time I saw a splashscreen take that long to
draw, the app was doing a million XSetForeground/XDrawPoint pairs,
instead of one single XPutImage.

Without knowing exactly what you're doing, it is difficult to suggest
improvements.

As far as I know, not much has changed since the ICCCM was last updated
~15 years ago, aside from newer apps preferring the UTF-8 encoding for text.

ICCCM: http://tronche.com/gui/x/icccm/sec-2.html#s-2
UTF8_STRING:
