x11perfcomp

X11PERFCOMP(1)						      General Commands Manual						    X11PERFCOMP(1)

NAME

       x11perfcomp - X11 server performance comparison program

SYNTAX

       x11perfcomp [ -r | -ro ] [ -l label_file ] files

DESCRIPTION

       The  x11perfcomp program merges the output of several x11perf(1) runs into a nice tabular format.  It takes the results in each file, fills
       in any missing test results if necessary, and for each test shows the objects/second rate of each server.  If invoked with the  -r  or  -ro
       options, it shows the relative performance of each server to the first server.

       Normally,  x11perfcomp  uses  the first file specified to determine which specific tests it should report on.  Some (non-DEC :) servers may
       fail to perform all tests.  In this case, x11perfcomp automatically substitutes in a rate of 0.0  objects/second.   Since  the  first  file
       determines  which  tests  to  report  on, this file must contain a superset of the tests reported in the other files, else x11perfcomp will
       fail.

       You can provide an explicit list of tests to report on by using the -l switch to specify a file of labels.  You can create a label file	by
       using the -label option in x11perf.

OPTIONS

       x11perfcomp accepts the options listed below:

       -r	       Specifies that the output should also include relative server performance.

       -ro	       Specifies that the output should include only relative server performance.

       -l label_file   Specifies a label file to use.

X DEFAULTS

       There are no X defaults used by this program.

SEE ALSO

       X(7), x11perf(1)

AUTHORS

       Mark Moraes wrote the original scripts to compare servers.
       Joel McCormack just munged them together a bit.
