# x11perfcomp(1)

X11 server performance comparison program

## 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)](/x11perf/1.md) 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.
