x-fontperf 1.1

x-fontperf is a small utility to measure font rendering/loading time in an x11 environment. Originally intended to see if there is any notable performance difference between a separate font server and local font rendering.
It actually does three different tests:
1) Loading the same font several times
Gives you an average loading time for this particular font. If you use a font already in use in your x-session this should be really quick as this font will be reused and not actually loaded again (cached)
2) Loading the same font in different sizes (incrementing)
Default is from 6 to 144 pixel. Interesting to see how rendering time increases with font size (see option -v)
3) Loading all available fonts
This should give you a good estimate on average fontloading time. Also a good test to stress your system and check if all fonts are loadable (see option -e)
Sample output:
x-fontperf -v

Verbosity can be increased in three steps by specifying -v several times. No-
tation -vvv is not supported. Use -v -v -v. Errors opening fonts are not shown
by default. Use -e to see them.
-n specifies the number of iterations for test 1. The default of 100 (shown in
brackets) should be ok for most systems. Increase/decrease values for fast/slow
systems
-min/-max specifies the minimum/maximum pixel size for test 2. Pixel sizes are
incremented by one.
The last block of arguments is for specifying the basefont to use for tests 1
and 2. These follow the standard x11 font naming scheme. Again: defaults are
shown in brackets.
