X11PERF(1)X11PERF(1)NAMEx11perf - X11 server performance test program
SYNTAXx11perf [ -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
performace. 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 win-
dows 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 oper-
ations include CopyPlane (used to map bitmaps into pix-
els), scrolling (used in text windows), and various stip-
ples 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 applica-
tions 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 num-
ber 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(1),
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 cor-
rectly 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 talk-
ing 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 approx-
imately 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 charac-
ters, but report on the number of characters per second.
Some window tests map, unmap, or move a single parent win-
dow, 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
X Version 11 Release 6.4 2
X11PERF(1)X11PERF(1)
rewritten to ease making comparisons between widely vary-
ing machines, to cover most important (and unimportant) X
functionality, and to exercise graphics operations in as
many different orientations and alignments as possible.
OPTIONSx11perf 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. Nor-
mally only useful for debugging x11perf .
-pack Runs rectangle tests so that they pack rect-
angles 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).
-all Runs all tests. This may take a while.
-range <test1>[,<test2>]
Runs all the tests starting from the speci-
fied 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
peform 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.
X Version 11 Release 6.4 3
X11PERF(1)X11PERF(1)-ddbg color-or-pixel
Specifies the color or pixel value to use
for drawing the odd segments of a Dou-
bleDashed line or arc. This will default to
the bg color.
-rop <rop0 rop1 ...>
Use specified raster ops (default is
GXcopy). This option only affects graphics
benchmarks in which the graphics function is
actually used.
-pm <pm0 pm1 ...>
Use specified planemasks (default is ~0).
This option only affects graphics benchmarks
in which the planemask is actually used.
-depth <depth>
Use a visual with <depth> planes per pixel
(default is the default visual).
-vclass <vclass>
Use a visual with of class <vclass>.
<vclass> can be StaticGray, GrayScale, Stat-
icColor, PseudoColor, TrueColor, or Direct-
Color. (default is the default visual).
-reps <n> Specify the repetion count (Default is num-
ber that takes aprox. 5 seconds)
-subs <s0 s1 ...>
Specify the number of sub windows to use in
the Window tests. Default is 4, 16, 25,
50, 75, 100 and 200.
-v1.2 Perform only x11perf Version 1.2 tests using
Version 1.2 semantics.
-v1.3 Perform only x11perf Version 1.3 tests using
Version 1.3 semantics.
-su Set the save_under window attribute to True
on all windows created by x11perf. Default
is False.
-bs <backing_store_hint>
Set the backing_store window attribute to
the given value on all windows created by
x11perf. <backing_store_hint> can be When-
Mapped or Always. Default is NotUseful.
