NAME
x11perf - X11 server performance test program
SYNTAX
x11perf [ -option ... ]
DESCRIPTION
The x11perf program runs one or more performance tests and reports how
fast an X server can execute the tests.
Many graphics benchmarks assume that the graphics device is used to
display the output of a single fancy graphics application, and that
the user gets his work done on some other device, like a terminal.
Such benchmarks usually measure drawing speed for lines, polygons,
text, etc.
Since workstations are not used as standalone graphics engines, but as
super-terminals, x11perf measures window management performance as
well as traditional graphics performance. x11perf includes benchmarks
for the time it takes to create and map windows (as when you start up
an application); to map a pre-existing set of windows onto the screen
(as when you deiconify an application or pop up a menu); and to
rearrange windows (as when you slosh windows to and fro trying to find
the one you want).
x11perf also measures graphics performance for operations not normally
used in standalone graphics displays, but are nonetheless used
frequently by X applications. Such operations include CopyPlane (used
to map bitmaps into pixels), scrolling (used in text windows), and
various stipples and tiles (used for CAD and color half-toning,
respectively).
x11perf should be used to analyze particular strengths and weaknesses
of servers, and is most useful to a server writer who wants to analyze
and improve a server. x11perf is meant to comprehensively exercise
just about every X11 operation you can perform; it does not purport to
be a representative sample of the operations that X11 applications
actually use. While it can be used as a benchmark, it was written and
is intended as a performance testing tool.
As such, x11perf DOES NOT whittle down measurements to a single
``HeXStones'' or ``MeXops'' number. We consider such numbers to be
uninformative at best and misleading at worst. Some servers which are
very fast for certain applications can be very slow for others. No
single number or small set of numbers are sufficient to characterize
how an X implementation will perform on all applications. However, by
knowledge of your favorite application, you may be able to use the
numbers x11perf reports to predict its performance on a given X
implementation.

That said, you might also want to look at
x11perfcomp(__appmansuffix__), a program to compare the outputs of
different x11perf runs. You provide a list of files containing
results from x11perf, and it lays them out in a nice tabular format.
For repeatable results, x11perf should be run using a local connection
on a freshly-started server. The default configuration runs each test
5 times, in order to see if each trial takes approximately the same
amount of time. Strange glitches should be examined; if non-
repeatable one might chalk them up to daemons and network traffic.
Each trial is run for 5 seconds, in order to reduce random time
differences. The number of objects processed per second is displayed
to 3 significant digits, but you'll be lucky on most UNIX system if
the numbers are actually consistent to 2 digits. x11perf moves the
cursor out of the test window; you should be careful not to bump the
mouse and move it back into the window. (A prize to people who
correctly explain why!!).
Before running a test, x11perf determines what the round trip time to
the server is, and factors this out of the final timing reported. It
ensures that the server has actually performed the work requested by
fetching a pixel back from the test window, which means that servers
talking to graphics accelerators can't claim that they are done, while
in the meantime the accelerator is painting madly.
By default x11perf automatically calibrates the number of repetitions
of each test, so that each should take approximately the same length
of time to run across servers of widely differing speeds. However,
since each test must be run to completion at least once, some slow
servers may take a very long time, particularly on the window moving
and resizing tests, and on the arc drawing tests.
All timing reports are for the smallest object involved. For example,
the line tests use a PolyLine request to paint several lines at once,
but report how many lines per second the server can paint, not how
many PolyLine requests per second. Text tests paint a line of
characters, but report on the number of characters per second. Some
window tests map, unmap, or move a single parent window, but report on
how many children windows per second the server can map, unmap, or
move.
The current program is mostly the responsibility of Joel McCormack.
It is based upon the x11perf developed by Phil Karlton, Susan
Angebranndt, Chris Kent, Mary Walker, and Todd Newman, who wanted to
assess performance differences between various servers. Several tests
were added in order to write and tune the PMAX (DECStation 3100)
servers. For a general release to the world, x11perf was rewritten to
ease making comparisons between widely varying machines, to cover most
important (and unimportant) X functionality, and to exercise graphics
operations in as many different orientations and alignments as
possible.

OPTIONS
x11perf is solely Xlib based, and accepts the options listed below:
-display host:dpy
Specifies which display to use.
-sync Runs the tests in synchronous mode. Normally only
useful for debugging x11perf .
-pack Runs rectangle tests so that they pack rectangles right
next to each other. This makes it easy to debug server
code for stipples and tiles...if the pattern looks ugly,
you've got alignment problems.
-repeat <n> Repeats each test n times (by default each test is run 5
times).
-time <s> Specifies how long in seconds each test should be run
(default 5 seconds).
-pause <s> Specifies how long, in seconds, to pause for between
each run.
-all Runs all tests. This may take a while.
-range <test1>[,<test2>]
Runs all the tests starting from the specified name
test1 until the name test2, including both the specified
tests. The testnames should be one of the options
starting from -dot. (eg) -range line100 will perform the
tests from the 100 pixel line test, and go on till the
last test, -range line100,dline10 will do the tests from
line100 to dline10.
-labels Generates just the descriptive labels for each test
specified. See x11perfcomp for more details.
-fg color-or-pixel
Specifies the foreground color or pixel value to use.
-bg color-or-pixel
Specifies the background color or pixel value to use.
-clips default
Default number of clip windows.
-ddbg color-or-pixel
Specifies the color or pixel value to use for drawing
the odd segments of a DoubleDashed line or arc. This
will default to the bg color.
