	To IBM rios testing consultant:

	   These tests are extensions to the x11perf tests, residing in
	   x11ext.

	   Tests should be run locally on the workstation, with as
	   little background activity (daemons, other users, ...) as possible.

					
	II. TEST SETUP/EXECUTION
	------------------------

	  1) The script file for running the extensions test is 'doit.ext.'
		The two environment variables at the beginning of the
		script file which can be modified to change testing
		parameters are:

		a) TIME=N;		# sets test repetition time to 'N'
					#  seconds (default is 30 seconds)
		
		b) REPEAT=M;		# sets number of times to repeat
					#  each test repeition (default is 2)

	     Extensions test:

		a) There are approximately 162 extension x11perf tests to run.
		   With a default time of 30 seconds / repetition and
		   a repeat factor of 2 (each test therefore being run for
		   a total of 60 seconds), the standard x11perf test should
		   take approximately 3.5 hours to run. If the repeat factor
		   is set to 1, runtime is approximately 2.0 hours. If the
		   repeat factor is set to 3, runtime is approximately 6.0
		   hours.

		b) To change the TIME or REPEAT parameter, edit 'doit.ext',
		   and modify the lines at the beginning of the file:

			TIME=30		# change '30' to new value
			REPEAT=2	# change '2' to new value

		c) To run, type:

			doit.ext


	III. BENCHMARK LOG OUTPUT
	-------------------------

	  Extensions:

	     1) Output is to the files `rios.ext.NNN' and `rios.ext.NNN.ps'
		 where 'NNN' is an integer (increments, starting at 0
		with each run), so output from multiple runs is saved.

	  In addition, all output is appended to the tar format file,
	    `riosdata.tar' (in the main directory) after test completion.
	
	  NOTE: As `riosdata.tar' contains data from all runs collected,
		 this file will need to be transferred offsite from
		 where the tests were performed.
		 If files can't be transferred offsite, hard copies of all
		 log files `rios.x11.*' and `rios.ext.*' must be obtained.
